A Few Good Men, but as above, i liked the film rather than her in it. She was never that good an actress, she just had less competition back then, if she was 20 years younger today she wouldn't have made it as a top star.
I've always thought of Demi as the female Tom Cruise ( I know, I know, that means there's two of them! ).......namely Pretty Vacant if you know what I mean but I have to give her some credit for her performance in Ghost which was perfectly suited for the role in that film........other than that she just never really had any screen presence for me so I was amazed she ended up as the highest paid female performer at one point and I'm not surprised she's not being offered any roles now to be honest!
