British director Sir Ridley Scott has claimed technology which allows people to watch films on mobile phones and computer screens is killing cinema.
Sir Ridley is also a producer on the Brad Pitt western showing in Venice
"We try to do films which are in support of cinema, in a large room with good sound and a big picture. But we're fighting technology."
"While it has been wonderful in many aspects, it also has some big negative downsides," Sir Ridley told reporters.
The director was among a host of stars attending the Venice Film Festival.
The film-maker, whose credits include Gladiator, Thelma and Louise, and Alien, was at the annual Italian event to introduce a digitally remastered version of 1982 cult classic Blade Runner.
The 69-year-old, whose new film - American Gangster - is released in November, also took a swipe at Hollywood studios.
"I think movies are getting dumber, actually. Where it used to be 50/50, now it's 3% good, 97% stupid.
"I'm not criticising Hollywood because I work there. But I'm saying this is the way it is, commerce is taking over art."
