US director Spike Lee has criticised Hollywood for its lack of originality while launching his latest movie at the Venice Film Festival.
Lee is currently shooting his fourth film with Denzel Washington
"I'm not naming any individual films but it's the worst it's ever been," he told reporters. "It's full of sequels and remakes of TV shows.
"There's no originality and that has not always been the case."
Lee is one of eight directors involved in All the Invisible Children, shown out of competition on Thursday.
Others include Ridley Scott, John Woo and Bosnia's Emir Kusturica.
Lee, who is currently shooting the thriller Inside Man with Denzel Washington and Clive Owen, said he was "not impressed" with Hollywood's current output.
However, the 48-year-old said he was "a hopeful person, so I'm hopeful things will change".
Recent remakes include film versions of TV shows The Dukes of Hazzard and Bewitched, both of which received lukewarm reviews from the critics.
Other films released this summer based on previously filmed material include War of the Worlds and Charlie and the Chocolate Factory.
All the Invisible Children was shot in seven countries and took four years to make. The film deals with young people growing up in different parts of the world.
Lee's segment, entitled Jesus Children of America, tells of a Brooklyn teenager with drug-addicted parents, who realises she is HIV positive.
"I wanted to help raise the awareness of HIV, particularly to kids," said the director.
"Children are being abused and forgotten all around the world, and I hope the film brings recognition to their plight."
Ridley Scott's segment, entitled Jonathan, tells of a photojournalist, played by David Thewlis, who regresses back into childhood.
Scott's daughter Jordan, who co-directed the short, said children "have this unique ability to transform any situation and make the best of even the worst circumstances".
