The 47-year-old Blade actor, who has four children with wife Nakyung Park, said that he regularly carries out research into different faiths to try to discover what his true purpose in life is.
"I like to read about different religions - Judaism, Islam, Christianity, Hinduism and Buddhism," MSN quotes him as saying. "I mainly buy books in my free time.
"It was actually my martial arts training that got me into it - after all it's quite spiritual. And at the theatre they always tell you what you're not. That actually made me wonder who I actually am."
