Kristen Stewart No Longer in Focus

Variety Kristen Stewart was attached to also star in the pic but when Smith became engaged in the project, Stewart fell off with the feeling that the age difference between the two would be too large a gap.

GossipCop Will Smith may replace Ben Affleck in Focus – but possibly not alongside Kristen Stewart.
Nearly four months after the Oscar winner left the project due to a scheduling conflict, Smith is said to be in “final talks” to take over Affleck’s role.
And, as Gossip Cop previously reported, Stewart was set to star in the movie, playing a young woman who teams up with a veteran con artist.

But while Variety says Smith has been cast in the older role, Stewart is reportedly out of the project.
The studio wants to find an actress closer to Smith’s age, says the outlet.
Gossip Cop has reached out to reps for confirmation.

The actress no longer plans to star in the comedy Focus, E! News confirmed Wednesday amid reports that Will Smith is in talks to take over the role vacated by Affleck in December.
There was some question as to whether Smith would then be Stewart's costar, but we're told that she actually dropped out of the project months ago.

THR Kristen Stewart is no longer set to star in Focus, a Warner Bros. heist project being directed by Crazy, Stupid, Love helmers Glenn Ficarra and John Requa. And as Stewart exits, the project could be landing a male star in Will Smith.
