Orlando Bloom looked every inch the rock star while shooting scenes for upcoming movie Sympathy for Delicious yesterday

The beefed-up actor showed off an impressive six-pack and selection of body art as he rocked out shirtless in front of a screaming audience at a theatre in downtown L.A.

Orlando was filming a sequence in which his rock singer character has a furious bust-up on stage with wheelchair-bound bandmate 'Delicious' Dean O'Dwyer played by Christopher Thornton.

The movie - which also stars Juliette Lewis - follows Delicious as he turns to faith-healing and mysteriously gains the power to cure the sick.

Sounds...intriguing.
