The footage, featuring actress Lily Tomlin and director David O. Russell screaming at one another, hit cyberspace late last week, and Clooney, who famously fell out with the moviemaker when they made Three Kings together, has been linked to the leak.
But in a statement released yesterday, the movie star wrote: "Contrary to popular opinion, neither the sound man, Ed Tise, nor yours truly sent in the David O. Russell tape.
"I saw it (footage) when we were working on Ocean's 12, and there have been quite a few copies traveling around town for the last couple of years. Any rumor that either of us put it on the Internet is simply false."
And Clooney is so keen to prove his innocence he's offering a huge reward if anyone can prove he was behind the leak.
He adds, "(I will) offer a million bucks to anyone who would prove otherwise."
