Jesse Eisenberg may come face-to-face with Mark Zuckerberg, the Facebook founder who he portrayed so well in The Social Network that it landed him an Oscar nomination, on this weekend’s Saturday Night Live.

Page Six reports that SNL is doing everything they can to get Zuckerberg on set for a cameo opposite Eisenberg. A source tells the paper that they’re hoping the guest spot will prove that Zuckerberg “has a sense of humor” and isn’t just the geeky programmer the film made him out to be.

Network was nominated for eight Oscars, including Eisenberg’s Best Actor nod, and also for Best Picture and Best Director for David Fincher.

Katy Perry extended her social network on Wednesday by visiting Facebook CEO and founder Mark Zuckerberg at the site’s headquarters in Palo Alto, California.
