I find it ironic that you list the real-life people that you would like to see in-game because of the fictional characters that they play in movies.
But I'll bite:
1) Kate Beckinsale: because she's hawt
2) Olivia Wilde: because she's hawt
3) Kate Upton: because she's hawt and can do the Cat Daddy Dance
You know what I will bite too what the heck..
Jessica Alba - Hot
Christian Bale - Batman
Charleze Theron - Again cos she is hot
