USA TODAY - Charlie Sheen saw inside Bill Murray's brain shooting A Glimpse Inside the Mind of Charles Swan III.
And he liked it.
The two worked together on Roman Coppola's quirky comedy, which comes out on Blu-Ray and DVD on May 14.
"He changed the way I looked at the world through his work," Sheen says of Murray in this exclusive clip from the DVD's extras.
"His brain opens up in like six different hatches when they call 'action,' " Sheen adds.
Sheen did admit that working with the idiosyncratic Murray had its challenges -- such as the way the Academy Award nominee delivers his lines.
"His rhythm is very bizarre," says Sheen of Murray. "You don't know if he's forgotten his line. You're working with him and I've known him for an hour, you don't want him to quit because of you, but you're about to interrupt him seven times in the same scene."
Then finally Murray would deliver the line.
Sheen left the gig with great respect for Murray.
"He was just dialed," says Sheen.
