Stewart Visits "X-Men: Apocalypse" Set, Reitman Recruits Fassbender as... The Dude?

Director Bryan Singer snapped a picture of Patrick Stewart and Jason Reitman during a visit to the "X-Men: Apocalypse" set and teased Michael Fassbender's role as the Dude in Reitman's upcoming live reading of "The Big Lebowski."

On his Instagram, Singer sits by Stewart and Reitman as he works; sadly, Stewart will not be reprising his role as an older Professor Xavier, at least so far as this photo would let you know. In the caption for the photo, Singer also writes that Fassbender will perform for Reitman's "The Big Lebowski" live reading later on that evening.

Trying to look intensely thoughtful, @sirpatstew and #jasonreitman visiting #xmen #apocalypse #xmenapocalypse set and reminiscing about our own #daysoffuturepast. Looking forward to "jasonreitmanlivereading tonight of #biglebowski with #michaelfassbender as "The Dude!"
