LOS ANGELES - ACTOR Christian Bale, known for his dedication to method acting, keeps going 'missing' on the set of his new film, said media reports on Thursday.

According to entertainment website Bang Showbiz, Bale has confused his fellow stars - Mark Wahlberg and Amy Adams - with his insistence on "getting into character" and refusing to be seen when he isn't filming.

"You only see him when it's time for his scenes. Other than that, no one has any idea where he is. He just goes missing," a source told E!

In the film, The Fighter, Bale portrays former crack addict Dicky Eklund in the movie - which follows the life of boxer 'Irish' Mickey Ward.

He has reportedly stunned people with his appearance. -- REUTERS
