Michael Fassbender could be saddling up with Natalie Portman for western film Jane Got A Gun.
The Shame star is "in negotiations" to star alongside the Black Swan Oscar winner in Lynne Ramsay's upcoming movie, reported Vulture.
Natalie is already on board to portray a married woman who is forced to ask an ex-lover for help, while Michael is tipped to play the ex-boyfriend in the drama, which has been written by Brian Duffield and is set to start production in early 2013.
The actress is also producing the film through her Handsomecharlie production company.
Michael, who has been filming Steve McQueen's period drama Twelve Years A Slave and Ridley Scott's The Counsellor, is also attached to several other films including the big-screen adaptation of computer game Assassin's Creed and a film based on Celtic warrior Cuchulainn.
