It's back to business for Matt Damon
, who returned to work in Cancun just a week after renewing his vows
with wife Luciana.
Stepping out at Saturday's Summer of Sony promotional event, Damon, 42, joined director Neill Blomkamp and costar Sharlto Copley to amp up their upcoming sci-fi flick, Elysium
Unlike White House Down costars
Jamie Foxx and Channing Tatum
, the actor didn't put his dance moves on display. We'll let it slide: Perhaps he was still tired from his St. Lucia celebration, which marked the 10 years he's known his wife in a Jimmy Kimmel-officiated sunset ceremony
"It was a very family-oriented and happy celebration," a source told PEOPLE at the time. As for the loved-up couple, "They were smiling and looked very happy together."
And their guest list was just as star-studded as the Sony gathering. Among those supporting the happy couple: Ben Affleck
and wife Jennifer Garner
, Casey Affleck and Don Cheadle.
