6. Tommy Flanagan
Another Glasgow-born actor, Tommy Flanagan has built himself an impressive filmography over the last 20 years or so, having starred in some pretty major films. He has a distinctive scar on his face as a result of having his face slashed outside of a club when he was younger which might have helped land him some of the more villainous roles he has played over the years.
What You May Know Him From: TV fans will known him well as Chibs from FXs biker drama Sons of Anarchy. Some of his notable cinematic roles include Morrison in Braveheart (shown above), Cicero in Gladiator, the explosive-loving Brian in Sin City and the expert assassin/master of disguise Lazlo Soot in Smokin Aces and its sequel.
