Matt Damon

The Cannes Film Festival is winding down, but the stars who have made appearances at the international event will have plenty of memories captured by camera lenses, and even a few A-list cell phones. Matt Damon stole the show with his multiple red carpet stops for Behind the Candelabra on Tuesday, while stars like Justin Timberlake and Garrett Hedlund buddied up for a quick iPhone snap. Steven Spielberg took in the massive crowd at the premiere of Inside Llewyn Davis earlier in the week, and Alessandra Ambrosio is just one of several celebrities who documented sightseeing adventures while off the red carpet.

Matt Damon and his wife, Luciana, took their girls for a sunny outdoor lunch at the Eden Roc Hotel in Antibes, France, yesterday. Matt sipped white wine and shared a sweet moment with his daughter Gia, showing her the water and pointing out some sights. Matt brought his clan along to Cannes while he promotes Behind the Candelabra, which debuts on HBO this Sunday. The family lunch was just part of a busy day for the actor — he attended a photocall for the film with his costar Michael Douglas and later hit the red carpet with Luciana for the movie's premiere, where he snapped photos of all the fun on his cell phone. In addition to his small-screen project, Matt has also been busy promoting the upcoming sci-fi flick Elysium. He screened trailers for the blockbuster in Mexico and Berlin late last month and will likely make the rounds with costars Jodie Foster and Diego Luna before the film hits theaters in August.

Matt Damon joined up with his Behind the Candelabra costar Michael Douglas to premiere their new film at the Cannes Film Festival today. Matt also had his wife Luciana by his side and they snapped pictures of all the action as they made their way down the carpet. Matt and Michael are screening their HBO project in the South of France before it officially hits the small screen on Sunday, May 26. Earlier in the day, Matt and Michael attended a photo call and a press conference. They have been doing quite a bit of press for the biopic, which follows Liberace, played by Michael, and his young lover, played by Matt. Naturally, a story about a couple had to involve love scenes, and Michael revealed in a recent interview he wasn't exactly put off by the idea of kissing one of America's best-looking actors. He said, "As far as making out with Matt, it’s not so bad. We rehearsed the scenes. For me, I guess the biggest thrill is, when I first saw it, after a few minutes, I really forget it’s Matt. Matt and Mike, you know? I just forget it’s us."

Matt is in Cannes after wrapping up filming for his upcoming film with George Clooney, The Monuments Men, in Germany. The pair celebrated finishing the film by having a boys weekend at George's Lake Como estate earlier this month.

The 66th annual Cannes Film Festival kicks off tomorrow, and we can't wait to see all the sexy celebrities hit the red carpet. Before we catch a glimpse of our favorite stars in the South of France, we're taking a look back at all the glamorous actors and actresses who have attended the cinema event in years past.

There have been plenty of great moments to capture, including last year's red carpet with Kristen Stewart, Garrett Hedlund, Jessica Chastain, and Shia LaBeouf; Leonardo DiCaprio and Cameron Diaz's photo-op back in 2002; and Charlize Theron's sexy outfit from 2004. Click through to see all the famous faces, and make sure to check back for all the updates straight from Cannes, where we'll be covering the most exciting premieres and parties.

George Clooney was joined by Matt Damon and producer pal Grant Heslov at Lake Como in Italy over the weekend. George and Grant were spotted riding motorcycles in Como, Italy, on Sunday together, and they later met up with Matt to catch a private plane out of Lugano Airport in nearby Lugano, Switzerland. The trip to Lake Como may have been a belated birthday celebration for George, who turned 52 last Monday but spent the day working on his new film, The Monuments Men, in Germany with Matt and Grant. He has another big film to look forward to as the trailer for Gravity, his upcoming project with Sandra Bullock, was released last week.

Matt and Grant are hardly the first celebrities who have spent time at the actor's vacation home — check out all the stars that have visited George Clooney's Lake Como villa!

George Clooney turns 52 today, and we're celebrating with a look at all the stars he's treated to getaways at his waterfront villa at Lake Como in Italy. In June 2004, George invited his Ocean's Twelve cast, crew, and loved ones, including Brad Pitt's then-wife Jennifer Aniston, to relax while shooting the sequel. Though George frequently gets in male bonding with friends like Matt Damon, Rande Gerber, and Bono at his Italian compound, his guests also include his girlfriends over the years. Click through to see who George has whisked away for lakeside romance, as well as which cast mates he regularly entertains.

George Clooney and an in-costume Matt Damon shared a laugh together on the set of The Monuments Men in Bad Grund, Germany, today. George has a good reason to be in a happy mood, as today marks his 52nd birthday. He didn't take any time off from work for his special day, and instead milled around the set with Matt and friend Grant Heslov in between shooting scenes. Yesterday, Matt and George shared a beer with friends outside their hotel in Ilsenburg. Matt is back to work on the World War II flick after taking a short break in mid-April to renew his vows to wife Luciana Damon, accept an award from Harvard, and promote his upcoming summer film, Elysium, in Mexico.

Both Matt and George have been working a lot over the past few months. The two may celebrate the completion of their latest project with a getaway to George's famous Lake Como estate in Italy — check out Matt, Brad Pitt, and more celebrities at George Clooney's house in Lake Como.
