Out of focus, indeed.

Less than a week after confirming his involvement, Kristen Stewart has lost her leading man, Ben Affleck, in their upcoming film, Focus. The actor reportedly dropped out due to his busy schedule.

Affleck “very much wanted to do the film, the timing just couldn’t be worked out,” per Variety.

Per Deadline, the Argo actor, 40, was originally cast to play Stewart’s love interest in the sexy comedy, about a veteran con artist who enlists the help of an inexperienced ingenue (Stewart). Other reports stated that the pair would film “passionate” love scenes.

Before signing off, Affleck expressed his excitement over the project, even calling 22-year-old Stewart “terrific.”

With the award-season buzz surrounding Argo, Affleck still has reason to celebrate. The political drama garnered five nominations at the 2013 Golden Globes (Jan. 13), including Best Picture and Best Director nods, and is already speculated to lead the way at next year’s Academy Awards.

As for Stewart? She’s currently promoting On the Road (also starring Garrett Hedlund and Kirsten Dunst), and is rumored to be starring in the sequel to Snow White and the Huntsman.

Kristen Stewart has finally settled on her next project.

The Twilight star will join Ben Affleck in the comedy caper Focus, for Warner Bros.

“I can confirm that [casting] rumor,” Stewart recently told The Huffington Post. “It’s a comedy. I’m really excited about it. We start shooting in April.”

In the film, Stewart will play a rising con artist who finds herself romantically entangled with a more experienced con man, played by Affleck. Word ‘round the campfire is, according to Hollywood Life, that Stewart and Affleck also share some steamy love scenes as well.

 Focus has yet to lock down a release date, but audiences can expect it in theaters sometime in 2014.
