Washington, July 28 : A new footage showing King of Pop Michael Jackson slurring and confused while filming for his movie `Miss Cast Away' has been revealed for the first time.

In the footage, nervous Jackson is seen biting his nails and mumbling lines during filming of the movie.

It was presented to news show `The Insider' by Bryan Michael Stoller, the director of the movie, who insists that Jackson struggled with his lines because he wasn''t "sleeping well" at the time.

Jackson is seen fiddling with sunglasses and his hair as he tries to act out the scene, and a hospital nametag bracelet can clearly be seen wrapped around his wrist.

"I didn''t know whether that was one of his signature things," Contactmusic quoted Stoller as saying. (ANI)
