LONDON (AP) -- George Clooney thinks something has gone wrong when the media prints celebrity rumor and innuendo as fact.

Clooney says a news story used to require two reliable sources but "that doesn't seem to exist as much anymore."

Clooney spoke Thursday at the London Film Festival, where one documentary in the lineup reveals how easily some newspapers can be duped into running fake stories about the famous.

The makers of "Starsuckers" fed false tips to British tabloids and then watched as some ran them as news. The hoaxes included a story about Amy Winehouse's beehive hairdo catching fire.

Clooney said he had sympathy for journalists, but the problem is "there's so little reporting any more."
