Margaret Rutherford in the Miss Marple movies.
Bo Derek in 10.
I agree. I completely believed that she was terrified, and barely holding it together - which is precisely the correct reaction to being trapped in a Stephen King novel.
Emmy Rossum in Phantom of the Opera. Drop-dead gorgeous looks and so innocent looking all at the same time.
Rosey O’Donnell as Betty Rubble. 
I adore Anjelina but think Mr. Eastwood miscast her in Changeling.Possibly it’s the fault of the makeup person but somehow she was a little *too *beautiful and contemporary looking.
On the other hand, I can barely watch Keira Knightley and almost didn’t see Atonement because of it. That would have been my loss as she is both stunning to look at and did a marvelous job with the role.
I think both Leonardo and Kate were utterly miscast in Titanic; she looking like his slightly older aunt.
Wrong: Uma Thurman. Period. Squinty-eyed, big-nosed, fish-lipped, man-jawed scrawny freak. I mean, she might be a nice PERSON in person, but she fucks up everything she appears in. Especially The Avengers. I don’t know if anyone could ever match Diana Rigg, but the number of actresses that could have outdone Thurman for the part must number in the tens of thousands.
Gwyneth Paltrow in “Sky Captain and the World of Tomorrow” – so wrong. Granted, gorgeous. Granted, a nice Veronica Lake look for the role. But she’s supposed to be feisty, and I don’t think she has a feisty cell in her body.
Rose McGowan in Red Sonja. I don’t think the movie ever got made, but damn, she had the look for the part.
Lee Meriwether was just the right choice to fill in for Julie Newmar in the old Batman movie.
Scarlet O’Hara should have been Bette Davis.
Holly Golightly should have been Marilyn Monroe.
Don’t be fooled by the name Schliemann assigned to the site where he did that dig. These people were there long before the Greeks actually got to Greece. I’m pretty sure those breasts aren’t to scale either.
If you’re talking about the Adam Sandler movie, she wasn’t in it which (IMHO) is perfect because I can’t stand her.
That’s a Mycenaean mural, not a Trojan one. So nothing to do with Troy. Which would make sense, Helen wasn’t Trojan.
Took the words right out of my mouth. The era and the character just begged to be played as the fast-talking, spunky girl reporter, but Paltrow was pensive and hesitant. I’ve always wondered if it was the actress or the director who decided to play the character that way.
And the irony is that Blythe Danner in her prime could have nailed it.
Kate Hudson was perfectly cast as Penny Lane in Almost Famous, very touching performance, you’d never know she was actually a great actress without having seen this film.
Emmanuelle Beart in Manon des Sources
