Michael Fassbender and Ryan Reynolds are among the stars set to be welcomed to Sundance London later this month.
Oscar nominee Michael and Green Lantern star Ryan also be joined by Michael Winterbottom, Rose McGowan, Jarvis Cocker, Steve Coogan and Gemma Arterton at the film festival.
The two-day event takes place at London's O2 from April 25 to 27 and will open with Frank, a comedy about a wannabe popstar who joins an eccentric band, inspired by comedian and musician Frank Sidebottom, and starring Fassbender and Domhnall Gleeson.
Steve will be promoting his sequel to The Trip with co-star Rob Brydon, this time called The Trip To Italy, while Ryan and Gemma are in town for crime comedy The Voices.
Jarvis is joining the Hybrid Vigour Documentary panel where he will discuss how British documentaries are pushing the boundaries in films about music, biographies and using archive film.
Sundance Institute's president and founder Robert Redford said: "That audiences in London have responded so positively to the films presented at the first two Sundance London festivals speaks to the power and universality of the stories told by our artists as well as the audience's openness to exploring new ideas."
