Which actors do you think could have had a great career but didn't for whatever reason?
I really think Amanda Bynes could have had a great career had her mental health not gotten so bad. Her career was just starting to take off right when it ended.
She was supposed to play Megan Fox's character in This Is 40. Judd Apatow would have been the perfect director for her to work with, and I could have totally imagined him eventually giving her a leading role in something.
It makes me sad whenever I think about it. She was so bubbly and charismatic on screen, and everyone who grew up watching her loved her.
