Viggo Mortensen

Kirsten Dunst and Garrett Hedlund continued their break from filming and caught up with another famous face in London on Thanksgiving. The pair grabbed a drink with their On the Road costar Viggo Mortensen and were spotted chatting with him outside Christopher's American Bar & Grill. The couple have been all over London in recent days. Kirsten and Garrett took a romantic stroll around town last week, and yesterday they were all smiles during a casual dinner. Their busy schedules will likely resume soon with Kirsten returning to the set of her latest film, The Two Faces of January, which also happens to star Viggo, while Garrett is reportedly among the hot leading men being considered to star in Fifty Shades of Grey — who would you cast as Christian Grey?

This week brought some very interesting casting news for stars Cameron Diaz and Chris Hemsworth. Both gained exciting new roles, and several more actors are in talks for new movie deals as well. Find out what surprising genres George Clooney and Sean Penn may be headed for, along with the rest of the week's biggest casting news in this roundup!

Kirsten Dunst and Viggo Mortensen filmed at the Acropolis together today in Athens, Greece. Viggo and Kirsten shared a kiss and linked arms as they shot scenes for their film, The Two Faces of January, in the historic city. Kirsten and Viggo star as a married couple in the thriller. The movie is based on a novel set in the '60s, making it the second project Kirsten and Viggo have shot in recent years based on a book. Their On the Road, a big-screen adaptation of Jack Kerouac's famous work, screened at both the Cannes and Toronto film festivals, and will also have a gala premiere at the AFI Film Festival in LA next month. Off screen, Kirsten is still dating her costar from that film, Garrett Hedlund. Garrett and Kristen have split their time between LA and NYC since meeting on the set in 2011.

Kristen Stewart and her On the Road cast mates gathered this morning for a photocall at the Cannes Film Festival. Kristen paired a white tee and black blazer with a pair of wild printed pants for the press session. She threw an arm around a Dolce & Gabbana-clad Kirsten Dunst for a series of girls-only pictures, then linked up with costars Sam Riley, Viggo Mortensen, Tom Sturridge, Garrett Hedlund, and Danny Morgan. Director Walter Salles was also on hand.Their movie just screened at the Grand Palais — make sure to check out our On the Road review.

Kristen's in France with the picture and her costars just ahead of her boyfriend Robert Pattinson's Cannes debut. He'll hit the Croisette himself with his David Cronenberg-directed Cosmopolis before the festival wraps up this weekend. Kristen and Robert aren't the only couple we're hoping to see making the rounds. Tom may have brought along his pregnant partner Sienna Miller, and Sam makes an adorable pair with his German actress wife, Alexandra Maria Lara. Kirsten was already hanging out with her boyfriend — she's dating costar Garrett.

Ever since the official trailer and On the Road posters starting rolling out, we've been waiting patiently for Kristen Stewart's individual poster for her character, Marylou. The wait is over! The new image came out today, and it completes the collection of the main characters in the onscreen adaptation of Jack Kerouac's classic novel. Now we get to compare her too-cool-for-school look (those sunglasses will be all the rage by the time On the Road gets released) to that of her costars, including Sam Riley, Garrett Hedlund, and Kirsten Dunst. Check out all the posters and let us know what you think!

Michael Fassbender was in a joking mood last night following his London premiere of A Dangerous Method! Inside 34 restaurant, he danced around with a Burberry Prorsum-clad Keira Knightley and their costar Viggo, as well as some other lucky attendees! Michael then sat at a piano to serenade the group that also included Keira's mom Sharman Macdonald. He got a piggyback ride from a friend out to his car, then proceeded to mock-fight with a group of photographers. Keira made a more low-key exit with her Klaxons musician boyfriend James Righton. It was an evening of fun during what's shaping up to be another busy year for Michael. It was recently confirmed that he'll work on another X-Men movie with director Matthew Vaughn.

Michael Fassbender reunited with his A Dangerous Method costars Keira Knightley, in Burberry Prorsum, and Viggo Mortensen this evening for a London premiere. The film came out in the US last Fall but is only just hitting theaters in Keira's home country. To promote the release, Keira's on the cover of GQ UK. An interview in which she discusses making the sex-themed David Cronenberg picture accompanies an equally racy photo spread. Speaking about her relationship with Klaxons musician James Righton and a recent reimmersion in work, Keira said she's in a great place. She commented, "I'm actually loving this bit right now — doing the work I'm doing, having the life I can have around it. Right now, it's really good."

We recently caught up with Keira to find out what she thought about working with Michael. Many thought Michael was overlooked when he didn't snag an Oscar nomination for his role in Shame, and Keira likely agrees. She told us of Michael's performance in Shame, "I think he's amazing . . . He's a phenomenal actor, and I think his performance in Shame is amazing. Talk about brave. I think it's wonderful."

Sony Pictures also played host to a Golden Globes bash last night! The stars from the company's many films got together to raise their glasses in honor of their many nominees. Rooney Mara of The Girl With the Dragon Tattoo had been nominated for best actress in a drama, an honor that ultimately went to The Iron Lady's Meryl Streep. She nonetheless mingled with Sony execs and sipped champagne at the bash in her dark Nina Ricci gown. Moneyball's best supporting actor contender Jonah Hill said hello to Sacha Baron Cohen, who was out supporting Hugo and its best director winner Martin Scorsese. A Dangerous Method best supporting actor nom Viggo Mortensen was in a great mood while talking about Spanish soccer, and Jodie Foster hung out with her sons Christopher and Charlie.

Keira Knightley showed some strategic skin last night at the BFI London Film Festival premiere of A Dangerous Method. The actress, decked out in Roksanda Ilincic, joined her costars Viggo Mortensen and Michel Fassbender on the red carpet along with their director, David Cronenberg. We were able to catch up with David and Michael at a recent NYC press day for the picture, which is out on Nov. 23. Michael said that he loves all the traveling his career requires at the moment, which is a good thing considering that he's been in NYC, San Sebastian, Toronto, and Venice during the last two months alone. He's doing double the jet-setting, since he has the Cronenberg film as well as Steve McQueen's Shame to chat up at festivals around the world.

The Dangerous Method reviews are so far mixed, but David is confident about his leading lady's work. At a press conference yesterday, David said he only wanted Keira to play the role of Sabina Spielrein. He said of Keira, "I think she's underrated as an actress. I took her seriously as an actress right from the first moment, and I was always looking forward to working with her, and I never offered this role to anybody else."
