Physical transformation key for Bale to enjoy acting

Mumbai: From the skeletal insomniac in The Machinist to the pot-bellied con artist in American Hustle, Hollywood superstar Christian Bale is that rare artist who stops at nothing to get under the skin of his characters.

This "transformation" is the key to his acting and keeps the process intriguing and interesting, Bale said.

"It's not necessarily what everybody does. I greatly admire people who are able to be themselves and be entertaining and be one thing all the time. There is an incredible talent to that. I don't have that.

"I like to see how much I can take myself out of each and every character I play. I actually enjoy that I don't have a particular technique and it change all the time. Sometimes it works, sometimes it doesn't," Bale, who is currently in India to promote Andy Serkis' Mowgli: Legend of the Jungle for Netflix, said.

He has spoiled Batman forever for other artistes with his masterful depiction of the angst-ridden superhero in Christopher Nolan's critically-lauded and commercially successful trilogy. He said people often attach the tag of "method actor" to him but the term is alien for him. Mowgli: Legend of the Jungle features performance capture and voice over by Bale.
