Christian Bale is unrecognizable with no hair and lots of facial hair as he gears up to prepare for his new role in "American Hustle."

Recent photos of the British actor at LAX airport shows that he has gained a lot of weight – a stark contrast to his weight loss for his role in "The Fighter", and a bald head.

The 39-year-old actor is known to take his acting roles very seriously and has changed his physique multiple times for his film roles.

Bale stars as Melvin Weinberg, a conman-turned-FBI worker in "American Hustle." Weinberg had taken part in a sting operation that led to several US Congressman's conviction in the '70s. The movie also co-stars Amy Adams, who he starred with in "The Fighter".

Bale started his acting career at the age of 13 when he starred in Steven Spielberg's "Empire of the Sun."

He also starred as Bruce Wayne / Batman in Christopher Nolan's Batman series; Batman Begins, The Dark Knight, and The Dark Knight Rises. He won an Oscar for Best Supporting Actor, a Golden Globe Award for Best Supporting Actor, and the Screen Actors Guild Award for Outstanding Performance by a Male Actor in a Supporting Role for his role as Dicky Eklund in "The Fighter."
