Apparently, Joel Edgerton isn't a big enough name draw for The Bourne Legacy so they've casted the next face of the Mission Impossible series, Jeremy Renner. The choice seems like an oddity considering his workload for the next few years - The Avengers, Hansel and Gretel: Witch Hunters and the aforementioned Mission Impossible: Ghost Protocol.
Renner is an Oscar nominee and a proven actor, it just doesn't seem like a great idea to cast an actor with that much on his plate (was Jmes Franco unavailable?), especially when that plate includes your main spy-film competition.
I wonder when Hollywood will realize that if you don't give little-known talents like Edgerton shots, then Jeremy Renner isn't around at all.
