Even though we didn't reboot any of her movies, you know Katherine Heigl would be cast in every single one of these. Because that's what Hollywood does: find a terrible, moderately sappy script and attach Katherine Heigl's tits to it. Maybe if they took Cate's advice, we could at least get some schadenfreude out of her horrendous movies.
Killers had potential, but they somehow let her and Ashton Kutcher BE the Killers. How you get those two on the same set and somehow manage to not murder them in every scene is beyond me. And is there any reason The Ugly Truth couldn't have been that Katherine has cancer? Please?
Oh, and I'd keep Knocked Up pretty much the same, because it somehow wasn't a terrible movie. I'd just make the birthing scene more like Alien.
