Ned Dennehy

While Irish actor Ned Dennehy hasn't necessarily found his "big break" quite yet, the character actor has quietly worked alongside the best in the business since making his screen debut in 1996. After popping up in several Irish TV series, he entered the Hollywood scene with a supporting role in the dragon-slaying adventure flick "Reign of Fire," starring Christian Bale and Matthew McConaughey. Dennehy quickly found his niche in period films and costume dramas, snagging bit roles in films like Guy Ritchie's "Sherlock Holmes" and Ridley Scott's "Robin Hood." A significant supporting part in Paddy Considine's 2011 drama "Tyrannosaur" helped stretch his acting chops beyond background work.
