One of the strangest moments of Oscars 2010 was the “Music by Prudence” acceptance speech that had producer Elinor Burkett pulling a Kanye.

Watch the video clip above, where director Roger Ross Williams starts the acceptance speech for “Music by Prudence” (which won for best documentary short), only to be interrupted by producer Elinor Burkett.

Salon.com has the scoop on the feud between Roger Ross Williams and Elinor Burkett that led to this Kanye moment at the Oscars.

Burkett explained: “What happened was the director and I had a bad difference over the direction of the film that resulted in a lawsuit that has settled amicably out of court. But there have been all these events around the Oscars, and I wasn’t invited to any of them. And he’s not speaking to me. So we weren’t even able to discuss ahead of the time who would be the one person allowed to speak if we won. And then, as I’m sure you saw, when we won, he raced up there to accept the award. And his mother took her cane and blocked me. So I couldn’t get up there very fast.”

Burkett further explains her role and the rift with Roger: “The movie was my idea. I live in Zimbabwe. Roger had never even heard of Zimbabwe before I told him about this. And you know, I felt my role in this has been denigrated again and again, and it wasn’t going to happen this time.”

Roger Ross Williams gives his side of the story: “Only one person is allowed to accept the award. I was the director, and she was removed from the project nearly a year ago, but she was able to still qualify as a producer on the project, and be an official nominee. But she was very angry — she actually removed herself from the project – because she wanted more creative control.”

Williams planned to give the speech solo: “I don’t know what they told her. The academy is very clear that only one person can speak. I own the film. She has no claim whatsoever. She has nothing to do with the movie. She just ambushed me. I was sort of in shock.”
