"Focus" is from writer-directors Glenn Ficarra and John Requa, the team behind "Crazy Stupid Love."
It was initially slated to reunite "Crazy" co-stars Ryan Gosling and Emma Stone, who both had scheduling conflicts. However, they'll soon be seen together again in "Gangster Squad."
Stewart will soon be seen in the Jack Kerouac adaptation "On the Road," and in the last film of the "Twilight" series, "The Twilight Saga: Breaking Dawn - Part II."
Affleck is currently starring in "Argo," and will soon be seen in Terrence Malick's "To the Wonder." He also has a number of films on the horizon including the gangster film "Whitey Bulger" with pal Matt Damon.
