Spike Lee couldn't let people down with his Michael Jackson documentary. The filmmaker has been working on Bad 25 - which examines the making of the late King of Pop's classic 1987 album - and was excited by the challenge of living up to the "pressure" of fans' expectations.

"It's good pressure. You can't let people down. If this had been sub-par I'd have been torn limb from limb," he said.

Spike has admired the "Thriller" hitmaker - who died of acute Propofol intoxication in June 2009 - all his life and admits his passing left him "messed up" for some time. "I'm a filmmaker, I love what I do and I grew up admiring and loving Michael Jackson. I saw him in 1969 on TV. He had a big afro and I wanted to be him. Michael's life deeply affected people and they miss him. His death messed me up for a month or two. He touched so many people," he said when asked why he made the film.
