The Venice Film Festival has kicked off in Italy with Birdman, a comedy drama about an actor trying to escape the shadow of a famous superhero role.
Former Batman actor Michael Keaton joined the rest of the film's stars on the Lido at the world premiere that launched this year's 12-day event.
Birdman is one of 20 titles up for the Golden Lion, the festival's main award.
French composer Alexandre Desplat heads this year's jury, which also includes the British actor Tim Roth.
Oscar-winning costume designer Sandy Powell and Palestinian film-maker Elia Suleiman are also members of the nine-strong panel.
Other films they will assess include Al Pacino's latest outing Manglehorn; Abel Ferrera's new film about Italian director Paolo Pasolini; and Good Kill, starring Ethan Hawke as a US military drone pilot.
The Look of Silence, Joshua Oppenheimer's follow-up to his harrowing 2012 documentary The Act of Killing, is the only UK co-production in the main competition line-up.
