Chris O'Donnell was seen busy at work on CBS' hit show 'NCIS-LA'. The actor - who was sporting a bloody gash on his forehead - was photographed in between takes on location in Pasadena, CA. Anyone a fan of Special Agent G. Callen? I actually don't watch the drama but am sure that Chris does his part justice.

Fans will be happy to hear NCIS-LA was renewed for a second season!
