The only reason I bring up this response isn't necessarily due to anything you have said but rather it seems that other posters point out her getting cut as evidence that she sucks as an actress.
Actually, the movie I was thinking of was indeed "Vanilla Sky" and the only reason I brought it up was not so long ago I read a debate that was discussing reasons why Tara had gotten cut.
I'm sure many scenes end up on the editing floor and of course that does not automtically mean so and so is a terrible actor. My opinion of Tara has an actress isn't very high anyway, after seeing her guest spots in some sitcoms and W/B shows.
