Jack Black would be happy to have his past lives read even though he doesn't believe in reincarnation.
The American actor-and-singer appeared alongside Shirley MacLaine in the movie Bernie, about a funeral director who befriends an elderly woman.
Shirley believes in reincarnation and has asked Jack to come to her New Mexico home for a regression.
"I don't really believe in that ooga-booga stuff, but I'll do it for the experience," he told British newspaper The Guardian.
Jack was raised in the Jewish faith but now classes himself as an atheist. He knows many don't understand such a turnaround, so likes to make a joke about it.
"Well, when I was a kid I remember hearing that a bar mitzvah was like your birthday times ten. And it was not like that at all. I got socks. So I turned to atheism," he deadpanned.
Jack and his wife Tanya have two sons and the actor has started going to synagogue again because of them.
The 43-year-old star is amazed by how much fatherhood has changed him. He can vividly remember the time he realised he was ready to have children.
"When I made [2003 movie] School of Rock I was still thinking I'm never gonna have kids, I'm too much of a kid myself, I want to wander the streets, like a vagabond," he recalled. "Then, during [2005 release] King Kong, I saw Andy Serkis with his wife and kids and I thought, that looks fantastic! He's really making it work. I started to get the hunger then, and it's been fantastic."
Although he enjoys acting, Jack's great passion is music. He is in rock band Tenacious D and is never happier than when he's on stage.
The star has plans for a "rock comedy summit" next year, which he wants to stage in Los Angeles. He hopes to enlist Zach Galifianakis to play keyboard on stage, with Jason Segel to show off his piano prowess. Jack is desperate to secure one other special guest.
"I was also thinking of throwing in the Hoff – but just one song, though. Just one," he said.
