MATT DAMON is guest-starring on this Sunday's episode of Showtime's "House of Lies".  (It's a show about a group of cutthroat management consultants that stars DON CHEADLE and KRISTEN BELL.)  Matt is playing a fictionalized version of himself, who's obsessed with out-doing GEORGE CLOONEY.  (Actually, maybe this isn't a FICTIONALIZED version of himself, just an exaggerated one.)

In a preview clip, Matt talks about wanting a charitable cause to improve his image.  He says, "I just basically need a cause that's about the size of Clooney's cause, only with bigger [boobs].  That guy, he puts on a Hawaiian shirt and they hand him [an effing] Oscar."

The episode premieres this Sunday night at 10:00 P.M.  (Here's a preview clip featuring Matt, and here's another one from the same episode.)
