Danny Boyle has settled on the heist thriller Trance as his next film, but it's going to have an odd schedule.  He plans to shoot it in 2012, break to direct the Summer Olympics, and then edit it with an eye towards a March 2013 release.  Michael Fassbender was rumored for the lead role he shady leader of a heist team gang partners with an art gallery assistant who masterminds the crime but then gets amnesia and forgets the location of the stolen portrait.  Fassbender ultimately passed on the role, but James McAvoy started circling another role in the flick.Twitch now reports that Boyle is courting Oscar-winner Colin Firth to replace Fassbender (not a step down by any means) and he's also looking at Scarlett Johansson for a supporting role.  Presumably, the role for Johansson would be the hypnotist the gang hires to get into the assistant's memory.  Twitch also reports that Zoe Saldana and Mélanie Thierry (Babylon A.D.) are also on his short-list for the part.  Hit the jump for a refresher on Firth and Johansson's other projects.After years of being stuck in supporting roles, Firth's Oscar-win has got him to the A-list and deservedly so.  He's starring opposite Cameron Diaz in Michael Hoffman's remake of the Michael Caine caper comedy Gambit and in February we reported that he had been offered the role of Henry Higgins in the remake of My Fair Lady.  He'll next be seen in the spy thriller Tinker, Tailor, Soldier, Spy.As for Johansson, she was recently cast in John Carney's music-oriented film Can a Song Save Your Life? She's also set to play a sexy alien in Jonathan Glazer's sci-fi drama Under the Skin.  She'll be seen later this year in Cameron Crowe's We Bought a Zoo and next summer she'll be reprising her role as Black Widow in The Avengers.
