Steven Soderbergh

Jude Law and Rooney Mara walked the red carpet at the Berlin International Film Festival today to premiere their project Side Effects. The costars debuted their thriller along with director Steven Soderbergh at the annual event, which has also brought out films like Les Misérables, Promised Land, and Amanda Seyfried's Lovelace.

Rooney repeated the stylish slicked-back bun she wore to the Side Effects screening and donned an embroidered black Valentino dress with a pair of Christian Louboutins. Jude and Rooney joined the growing list of stars at the Berlin Film Festival to present their film after they premiered Side Effects in NYC with Channing Tatum and Catherine Zeta-Jones at the end of last month.

Jude Law and a Band of Outsiders-clad Rooney Mara teamed up in NYC last night for a special screening and Q&A session for their new Steven Soderbergh film, Side Effects. Rooney and Jude were joined by Steven himself, as well as their costar Vinessa Shaw and screenwriter Scott Z. Burns. Missing from the panel, though, were leading man Channing Tatum and Catherine Zeta-Jones.

It was a busy day for both Rooney and Jude. He managed to also fit in a stop by Late Night With Jimmy Fallon. Jude and Jimmy reminisced about their first fights as children and chatted about Side Effects, which arrives in theaters Feb. 8. In particular, Jude gushed about Rooney, whom he referred to as "a very cool lady" and a "great actress." Rooney, meanwhile, had a family night. She stepped out to support sister Kate Mara at her debut of the new Netflix series House of Cards.

Matt Damon and Michael Douglas took the stage at the HBO Winter 2013 TCA Panel yesterday in Pasadena. Michael and Matt, who costar in HBO's upcoming Behind the Candelabra, were at the Langham Hotel with producer Jerry Weintraub and director Steven Soderbergh to chat up their Liberace biopic. The TV film is based on the story of Liberace, portrayed by Michael, and his five-year relationship with the much younger Scott Thorson, played by Matt.

The gang spoke about the project yesterday at the TCA and about their struggles to make the project as accurate as possible because it was based on the stories of real people. Matt said about the Liberace film, "There are aspects of their relationship that were absurd, but for me, it just kind of pointed out that there are aspects of all of our lives that are absurd . . . What it felt like was if this was a relationship between a man and a woman, you’d feel moments like, 'This is too intimate — maybe I shouldn’t be here.' But it’s between a man and a man, and I’ve never seen that movie before. So it was fun, but we weren’t giggling about it. We took it very seriously. These are people’s lives, and we wanted to get it right."

Matt spent the afternoon focusing on his small-screen project, though his latest big-screen endeavor, Promised Land, arrived in theaters across the country yesterday, too. The project was out in limited release a week ago, but has now opened widely — check out so-so Promised Land reviews.

Blake Lively was decked out in Dolce & Gabbana last night for the NYC premiere of Haywire. She's not in the movie, but leads Ewan McGregor and Gina Carano were there from the cast, along with director Steven Soderbergh. The picture hits theaters tomorrow on Jan. 20, and so far the Haywire reviews are great. Justin Bartha and Elizabeth Banks also rolled through to check out the screening, and joined the festivities at the afterparty, held at Sons of Essex.

Blake and Steven will work together soon, though. It was recently announced that Blake will star in Soderbergh's The Side Effects opposite Channing Tatum and Jude Law. For now, it's Gossip Girl that's Blake's main focus, as is her relationship with Ryan Reynolds.

Matt Damon arrived hand in hand with his lovely wife, Luciana, at tonight's NYC premiere of Contagion. The couple posed for photos before Matt went on to meet up with Marion Cotillard and director Steven Soderbergh on the red carpet. It was a wild day for Matt, who kicked things off before dawn with appearances on The Today Show and Live With Regis and Kelly. Matt touched on the seriousness of infectious disease, the focus of the film, and then switched gears to a lighter subject when he revealed he'll be dropping three of his daughters off for the first day of school this week. Marion arrived on the East Coast with her son, Marcel, recently and was also busy hitting the talk show circuit. She dropped by Late Night With Jimmy Fallon this afternoon and is scheduled to visit The Daily Show With Jon Stewart tomorrow. Matt and Marion's costar Gwyneth Paltrow stepped out to promote the film in Venice over the weekend, but tonight she missed out on the Big Apple screening. Instead, Gwyneth partied with friends in London.
