Gemma Arterton & Andrew Garfield Joining Michael Mann's Capa

Gemma Arterton revealed to Total Film (via ThePlaylist) that she is replacing Eva Green in Michael Mann's Capa. The film is based on the life of photographer Robert Capa and the novel Waiting For Robert Capa written by Susana Fortes. Arterton also says that Andrew Garfield is lined up for a role I assume Capa.

It's curious when it will actually happen as Mann's Big Tuna sounds like the better project and is currently being scripted by Sheldon Turner (Up In The Air). It would make sense that both actors could be ready to make Capa after their two large productions Spider-Man (Garfield) and Wrath of The Titans (Arterton).
