Worst acting job/worst character in Prometheus?

They were all good acting as forgettable characters. 

I have to say Nooni. I already wrote tomes about why I hated the character on other threads and am tired of typing it now. "Because I choose to believe" lol

The pilot who was not Benedict Wong

Id say Ford.Kate Dickie is great(just see The Witch and Game of Thrones)but her character contributes practically nothing to the plot.I didn't know her characters name  until after a few viewings(i dont think anyone actually says it,its only seen on her cap as far as i know).I should also say maybe shes not the worst character,just the most forgettable of the primary cast.

I think Noomi's acting was a bit wooden and over-acted at times (see vomiting out of cryo scene). It's clear she was primarily cast because of her facial similarities to a young Sigourney. Don't get me wrong, I like her, but think some of the scenes appear almost like they were one-takes just filmed to add the dialogue and small amounts of exposition (of which, fortunately, there isn't a lot of in the film).

Milburn's accent started with a pretty pronounced drawl (when introducing himself to Fifield - 'Milburrrrrrrrrn, Bioloooooooogeeeeeeeee), which subsequently disappeared - but his acting was good.

I think it's shame we didn't see more of Chance and Ravel. They had some great banter between them (and with Janek) and really could have been used more to add more depth to the movie and crew (and justify why they'd just decide to kill themselves with Janek, just like that).

I agree, Ford could have been good, but she was relegated to, essentially, Engineer fodder.

I think Guy Pearce gets a bad wrap. We all know why he was cast, but the younger Weyland scenes were dropped. I think his scene with Vickers is particularly good (aside from the 'you are my Father' bit of dialogue - expected Vickers to pull out a lightsaber and strike him down).

I also think Logan Marshall-Green wasn't as bad as all that. His character was annoying as hell (too enthusiastic, hyped up) and there's no doubt his parts, generally, weren't essential to the plot. Like Ford, he was really relegated to a lab rat/sperm donor.

Marshall-Green did what was required of him as per the script.  Couldn't really fault his acting.

Kate Dickie got stuck with some rubbish dialogue.

As has been mentioned, if there was anything to fault it was Millburn and Shaw being of no fixed accent.

Yeah @S.M - I think that's called a 'fakeccent'!!!

I think Rapace only got a look in because her performance in The Girl with the Dragon Tatoo trilogy piqued Scott's interest. Look how easily she's been sidelined.

They did their best as professional actors, perhaps intimidated by the stature of Scott. They do not yet have the powers of a Brando, who could challenge the writing.

Indeed the writing is to blame. I'm no screenwriter but it was just obvious most of the characters had no plot significance, not even alien bait. Contrast that to Alien, where everybody--even the gaddam cat--were pivotal to the plot.

Good stuff here, I'd forgotten how bad Ford was and how awful her part was. Heck, 7/8 of the crew wasn't even needed for the film, lol.

The dialogue was just terrible. Disappearing and reappearing accents, Fifield's wolf howl, Holloway's deep thoughts (God does not build in straight lines....It's Christmas, and I want to open my presents).

I'd have to narrow down the poorest acting to Ford and Vickers...with Vickers given a pass as she was supposed to act wooden to get us to think "Is she or isn't she?"

Ford wins. Next time a giant, bald alien charges you after tearing the head off a synthetic and beating a geriatric man to death with said head, try to act a little more terrified as opposed to looking like you're having a seizure or you've just soiled your Depends.

I don't think that anyone did a really bad acting job. Holloway was a dislikable character though, and almost deserved what David did to him. Fassbender did the best acting job, I think.

@chli you are certainly correct about Fassbender. He essentially carried that movie, and is therefore one of the primary reasons A:C focuses on him.

That’s a tough one since most of the characters were so poorly written and scenes that were edited in such a disastrous way which made them seem worse so I don’t have words for it. I dislike Shaw, mainly because of her religious idiocy (there are too many moronic quotes to choose from that she said) and lack of reason. She was the worst character but that isn’t to say that she did the worst acting job because there were so many bad characters and maybe they did what they could being what they were given to work with.

I would like to add to what MuzzeleNZ said about Chance and Ravel. It isn’t like their characters sucked but they were in it too little so I am not sure what they really contributed to in the movie except for being some crew members that helped the captain. Unfortunately, they didn’t do a very good work with the scene when they were about to stop the Engineer at the end “I pay you on the other side”, smile. I was like “WTF? Shouldn’t they express some fear, sorrow, or what ever?” They are about to go on a suicide mission and they act like they are talking about a soccer match that they watched. They were almost impossible to get some sympathy for but at least they were not annoying like Milburn, Fifield, or Shaw which probably is a plus but that doesn’t really say a lot.

Fassbender was the most interesting character and I also liked the captain (Janek) but the rest were either boring (Holloway), stupid (Shaw), or didn’t offered that much to the story (for example Ford).

I agree with a lot of posts here whether it's the acting or dialogue.

Sometimes it was downright horrible, other times misplaced, forced or exaggerated.

It wasn't bad throughout (although not far from), I basically liked everything by Fassbender, not just what he said but how he delivered the lines (a fine example of underperforming, like Gosling in Drive or Marlon Brando in basically everything as opposed to exaggerated or forced acting) 

I also liked moments when:

- we followed David aboard the Prometheus at the beginning, almost certainly Ridley's idea.

- the atmospheric analysis of LV-223's surface by the crew stating how harsh the environment was, a suspension builder.

- the briefing of the mission in itself as context and purpose to the plot (despite the rather silly content, religious and shockingly stupid reply from Rapace and childish response from "professionals" who are chosen to gather results btw)

- Elba when he finally got some acting energy on the set and went from occasionally bored captain (despite critical events prior to the crash wtf captain) to super alert.

- Noomi's abdominal pain, her stress and confusion was convincing (unfortunately by this time I'd already lost my "faith" in the film). Her all too religious beliefs (read: indoctrination) as the lead motive to pursue "answers" was ridiculous, as was her accent. 

I pay you on the other side”, smile. I was like “WTF? Shouldn’t they express some fear, sorrow, or what ever?” They are about to go on a suicide mission and they act like they are talking about a soccer match that they watched

Exactly how I felt, what happened to the credibility here? 

If they were that prone to fear then they got into the wrong line of work (that being said, Fifeld and Milburn seemed pretty succeptible to fear).

Fifield just wanted to get paid, ala Brett/Parker.

Milburn, I'm convinced, was just an idiot.

Noomi Rapace is a very good actress, I have been impressed by her many other roles. However, I thought that she was totally miscast as Shaw, I felt zero empathy towards her and found her character impossible to like!

Apart from Michael Fassbender as David, who was outstanding, the other actors were underused. Both Vickers and Janek had more scenes which were cut, such a pity as it gave them both a touch more depth.

I liked Janek, Chance and Ravel, but as I said...underused.

Still, none of that stops me from loving the film as a whole!

The writing was not at its best... it was a bit more goofy and not fitted a dark Sci-Fi universe... so many kind of goofy dialog that did not fit within this kind of movie.... where as Alien was more solid... Spaights was similar.. as far as Characters and Dialog...  So its like AVP Characters vs AVPR i guess.. or like a Alien 3 vs Alien R as far as dialog and characters written that suits more of a Guardians of the Galaxy type Sci-Fi and not a Serious one.

Most of the Characters Faults are to do with the Characters, as written and then as Ridley Scott chose to portray them.

Holloway was a Nob-head... (Dick-Head) but guess what you get people like him in real life... i know someone who would actually make him seem a pretty decent down to earth guy lol

If you ever watch shows like Big Brother, Geordie Shaw, Jersey Shore you see some people are like that...

Milburn and Fifield was a Plot Device.. and could been done better the same goes for Ravel and Chance...

Ford was limited again to her Character and Katie Dickie can act better than that... so can Sean Harris (Fifield)

Proof in the poor Character writing is with Vickers too... some scenes that portrayed her character different and these never worked well..... the softer side of her.. and the "are you a robot" etc....    Charlize Theron deserved better....

I am just hoping Blomkamps Charaters are not wrote in the same fashion as we will surely see the Flaws that Miss Weaver has not saying shes bad... but Theron and Rappace are better actors overall.

The only real Solid Characters really was Janek, Weyland and David.

Weyland had limited time, but his Character fitted well with what his Character was intended for and apart from Makeup i think Guy Pearce did as good as job needed.... i am sure if we had longer scene... where Shaw and Holloway would meet Weyland before there journey (as intended in earlier drafts) then Weyland would have come off as a good character.

Iris Elba did a good job of his character but he was given a good character to play.

The same goes for David... but none the less Fassbenders performance was very good.
