People who's presence in a good movie puts you off.

Ditto Hugh Grant, Nicolas Cage and DiCaprio. I liked DiCaprio in Gilbert Grape. In fact, I thought the kid really was retarded. But everything I heard about his antics IRL since then has really put me off him; like refusing to put out a cigarette when informed that he was in was no-smoking restaurant, and basically behaving like a spoiled, entitled little prick.

In addition, let me add Jack Nicholson. Plays The. Same. Jack. Every. Time. And his “Jack” character is an asshole, which suggests rather strongly that Jack is an asshole IRL.

After seeing Sideways I see a self-centered wine snob and a selfish moron every time I see Paul Giamatti and Thomas Haden Church, although I had seen them in other things before.

Most of the wacko’s, like the hardcore scientologists (Cruise, his vacant bride, Kirstie Alley, the afore mentioned Nick Cage), Shirley MacLaine I can’t see the character they’re portraying, just the nutcase.

Oh one or two . . .
Kirsten Dunst
Ellen Page
Sandra Bullock
Ryan Reynolds
Will Farrell
Jennifer Connelly
Vince Vaughn
Rob Schneider
The guy from The Notebook
Casey Affleck
Samuel L. Jackson
Renee Zellweger
Helena Bonham-Carter
Halle Berry
Jason Biggs
Any modern American child actor (there are such great examples of amazing child acting in older and foreign films)

One who’s teetering on the edge:

Denzel Washington

Another vote for Helena Boring Carter and Tom Hanks and a new one for Andi McDowell who ruins every movie she appears in.

Sandra Bernhart
Paul Giammati
David Caruso ( our generations’ William Shatner)
Hugh Grant
Andie Macdowell

For me it’s Kris Kristofferson. Why can you always hear him breathing??

Denzel’s always been one for me as well. I do like him and I think he’s a good actor but I can’t stand actors that seem to be just “being themselves” in a movie. He’s always seemed slightly annoyed with white people to me in a big way. Don’t know if that makes any sense.
Kirsten Dunst don’t see no pretty no how, she’s just like some scabby kneed trailer trash girl behind the 7 11

And Uma, though I like her to a degree I don’t get how she’s this ravishing beauty, when they do close ups on her face ala Pay Check I’m like “Ok the chick is a piece of action but when you zooom in that close its like oh wow she’s really not that pretty is she?”

When I read your first post, I thought you were talking about John C. McGinley in the made for tv movie, Intensity. I remember when I first saw that, he creeped me out so much that I avoided anything else he was in for a long time. Eventually I started watching Scrubs, and at first he made me cringe, but now Dr. Cox is my favorite character.

How is it possible that no one has mentioned Rebecca Pidgeon?

Ryan Reynolds and Shia LaBeouf.

I liked Reynolds in comedies. I don’t like Reynolds taking up screen time in my action flicks.

As for The Beef… what the hell is this two-bit, teeny bopper doing as a main character in ANY movie? And why is he invading my most beloved series of all time???

The Beef is going to actually be hamming it up in my Transformers and Indiana Jones? This can’t be real!

Keanu in the Kenneth Branagh version of Much Ado About Nothing.
For goodness’ sake! What sort of weird/awful casting was that? Denzel kinda pulled it off, but Keanu was DREADFUL. I love the movie, but groan aloud through Keanu’s scenes. The other actors deliver their lines so beautifully and MEANINGFULLY, and he just yaps at the camera.
Bad!

Another vote against Tom Hanks and Jack Nicholson.

Chris Tucker
Vince Vaughn
Martin Lawrence
Owen Wilson
Adam Sandler
Quentin Tarantino
Kathie Griffin
Madonna

Ooh, that’s a good one. Fits the OP perfectly since he only acts in good movies and he’s a terrible actor. The guy really needs to learn how to stay behind that camera. Ditto Shyamalan, though many (including myself) would dispute the “good movies” part.

Yes yes yes. He very nearly ruined Sukiyaki Western Django for me… I know it was pretty much compulsory to give him a cameo, given that it’s a masterfully self-referencing tongue-in-cheek B-movie and there’s a history of mutual admiration he could leverage to get more screen time… but EW.

To further add to the list:
Dakota Fanning - WE GET IT. You’re precocious. Now please go away.
Nicolas Cage - I’ve seen rocks with more emotion and charisma. Please also go away.
Meg Ryan - Yes, you’re cute and quirky. You should also go away.
Will Ferrell - It was funny the first time you did it. And maybe the second time. But it’s been done 20 times now… GO AWAY!

What? 33 posts and no love… er… hate for Jeff Goldblum. God does that man suck.

In that same vein, how can it be possible that no on has mentioned Lindsay Crouse?

Juliette Lewis. She’s been in some good films, but she bugs the shit out of me. I’ve never seen anything that made me think that she has any: a) attractive qualities, or b) brain cells. She looks like a trailer-park skank and talks like a real-life Kelly Bundy in most of the interviews I’ve seen.

And she’s a Scientologist!

Ack! Bleeeaaah!
I don’t actively search out which actors = scientology, but I’ve had one too many surprises come up lately.
[Johnny Carson] I did. Not. Know that. [/JC]
I don’t like the girl much anyway, but even though it’s not the case, it seems like those OGDAMN scientologists are popping up everywhere!
Maybe I need some time with an e-meter.

Could a mod fix the thread title?

I was going to say Bo Derek, but I can only think of one halfway-decent movie she’s been in, and she was actually perfect for the part.

And somebody beat me to Rebecca Pidgeon. I really get tired of looking at her one facial expression.

Some of y’all seem to have a wee bit of trouble with the concept that an actor pretends to be somebody he’s not.
