The exes are among the scores of stars slated to attend the famed Cannes Film Festival, which runs from May 14 to 25 and revealed its lineup in a press conference Thursday.
Pattinson, 27, has two films in contention: The Rover, a gritty drama set in a near-future Australia, and Maps to the Stars, a Hollywood-skewering drama costarring Julianne Moore and John Cusack. Stewart, 24, will be seen in the drama Clouds of Sils Maria with Juliette Binoche.
The royal biopic Grace of Monaco, starring Nicole Kidman, is slated to open the festival on May 14. A total of 49 films are being shown at the prestigious fest, which is considered a key launching pad for films with box-office and awards-season hopes.
The 18 films in competition will be judged by a jury headed by Jane Campion, the first female director to win the event’s coveted Palme d’Or prize, for 1993’s The Piano.
Among those who are expected to be on the red carpet May 14-25:
• Ryan Reynolds stars in the psychological thriller The Captive as the father of a kidnapped girl.
• The Disappearance of Eleanor Rigby, a two-part drama about a young married couple living in New York, stars James McAvoy and Cannes favorite Jessica Chastain.
• Oscar winner Cate Blanchett returns to the Croisette for her voice work in the out-of-competition How to Train Your Dragon 2.
• Channing Tatum and Steve Carell hope to launch Oscar buzz for Foxcatcher, a drama based on Olympic wresting gold medalist Mark Schultz’s autobiography.
• Hilary Swank costars with Meryl Streep and Streep’s daughter Grace Gummer in The Homesman, a Western directed by Tommy Lee Jones, who also costars.
• The Artist, which started its award run at Cannes in 2011 and went on to win the Best Picture Oscar, will stage a mini-reunion at this year’s festival. Director Michel Hazanavicius and his leading-lady wife, Bérénice Bejo, return with their follow-up, The Search, a French-language war film set in Chechnya and costarring Annette Bening.
• At 83, iconic French director Jean-Luc Godard will also have a film in competition – in 3-D, no less: Goodbye to Language.
