3. KATHERINE HEIGL AS ALISON SCOTT IN KNOCKED UP (2007)

Stoner? No
Complex says: When the millions stopped pouring in and the smoke cleared, Heigl let her displeasure about being the straight-laced Debbie-Downer character in the movie be known. And she was right. She wasn’t funny at all in this.

Still, Heigl is about as beautiful as you can ask a woman to be, so, honestly, we didn’t give a fuck about her general lack of hilarity (here or in any of her other “comedies”).
