Roles she turned down

"Knocked Up" due to creative differences. "Silver Linings Playbook" due to scheduling conflicts. She was also considered for "Phantom of the Opera".

I wonder what the creative differences were?

According to IMDB trivia: "In an interview, she revealed that she objected to Judd Apatow's plan to use footage of a real birth."

She also turned down Alice in Tim Burton's Alice in Wonderland because she felt it was too similar to previous roles. She was cast as Mirana the White Queen instead- and I LOVE HER in this role (not that I don't also love her in other roles ;) )

Also, the lead in "Laggies (2014)"

That, admittedly, is a bizarre reason to turn down a role.
