Mark Wahlberg Is Beat Up, Christian Bale Is Just Beat! - Photos

Mark Wahlberg made Robert Pattinson's recent battered face look like a scratch when he emerged covered in fake blood on Wednesday.

The actor was also sporting an impressive six-pack as he filmed scenes for new movie The Fighter at Tsongas Arena in Lowell, Massachusetts.

The same can't be said for his co-star Christian Bale, who looked like he was working on a sequel to The Machinist, rather than a boxing movie.

The Batman star looked unhealthily gaunt as he appeared on set in baggy clothes that hung off his skinny frame.

The Fighter chronicles the journey of 80's boxer "Irish" Micky Ward (Wahlberg) to the world light welterweight title, with the help of his step-brother Dicky (Bale.)

Christian's character is also a drug-addicted former boxer - hence the dramatic weight loss.
