Top 20 Actors That Turned Down Incredibly Massive Roles

6. Katie Holmes – Buffy Summer

This one is a bit surprising, and Holmes’ reason for backing out is even more surprising. Katie Holmes was originally offered the role of famed vampire hunter Buffy Summer, but turned it down. The actress decided that she would rather finish high school than stay up late killing vampires. We gotta wonder if she is regretting that move now, especially once Angel entered the show. Sarah Michelle Gellar got the role of Buffy instead.
