Carell's Foxcatcher at LFF premiere
Steve Carell and Sienna Miller are to walk the red carpet at the UK premiere of their new film, Foxcatcher, at the 2014 BFI London Film Festival.
Bennett Miller's dark drama, which stars Steve as killer John du Pont, has been named as the American Express gala on October 16.
The film's director will also attend the event, which will take place at the Odeon Leicester Square.
Based on true events, Foxcatcher tells the dark and fascinating story of the unlikely and ultimately tragic relationship between the eccentric multi-millionaire and champion wrestlers Mark Schultz (Channing Tatum) and his brother Dave (Mark Ruffalo).
Bennett said: "I'm thrilled that Foxcatcher will be playing the LFF and I'm thrilled to be attending. I suspect Britons will have a special relationship with this film."
The festival's director Clare Stewart added: "Featuring enthralling performances from its entire cast and directed with unswerving rigour, Foxcatcher not only confirms Bennett Miller as one of the world's most significant contemporary filmmakers, it powerfully demonstrates the clarity of his vision: get to the truth by creating fiction out of fact."
The 58th BFI London Film Festival, in partnership with American Express, runs from October 8 to October 19. The festival's full line-up will be announced on September 3.
