The 'Argo' director is reportedly set to work with Stewart in romantic comedy 'Focus' and Affleck said he would jump at the chance, reported Daily Star.
"I'm hesitant to get into casting stuff because I don't know what's finished or isn't because people come in and out of things all the time. But she's terrific and hopefully it will work out," he said.
Stewart recently revealed she is desperate to land another role now that 'Breaking Dawn Part 2', the final movie in the 'Twilight Saga' franchise is finished.
