Michael Jackson's mother has said it is still too soon for her to watch the forthcoming movie This Is It.

The film, which is released on October 28, follows the late singer as he prepared for his ill-fated comeback gigs in London.

Fans around the world have scrambled for tickets to see the movie, which will only have a two-week run in cinemas.

But the singer's mother Katherine and sister La Toya have said it is too early for the documentary to be released.

"I don't think I can bear to look at it right now," Katherine told Access Hollywood. "But eventually in time, I will watch it."

La Toya said: "I have no plans to see it. It's a bit too soon for me. It really is."

Directed by choreographer Kenny Ortega, This Is It has been created from over 100 hours of behind-the-scenes footage of Jackson rehearsing.

The singer died on June 25 - just two weeks before his comeback was due to begin.
