Last Tango in Paris director Bernardo Bertolucci – whose debut film, The Grim Reaper, showed at the festival in 1962 – will lead the jury for this year’s Golden Lion for best film.

US director William Friedkin, best known for his films The French Connection and The Exorcist, will also receive a lifetime achievement award.

He described the festival as his “spiritual home”, adding he would accept the honorary prize “with gratitude and love”.

Alfonso Cuaron’s film features George Clooney and Sandra Bullock as astronauts attempting to return to Earth after debris crashes into their space shuttle, leaving them drifting alone in orbit.

The rest of the festival line-up is yet to be announced, but films being tipped to be screened include Under the Skin, starring Scarlett Johansson as an alien and Twelve Years a Slave, the latest film from British director Steve McQueen starring Brad Pitt, Chiwetel Ejiofor and Michael Fassbender.
