Matthew McConaughey (Dallas Buyers Club)
Matthew McConaughey, who first gained attention for his breakout role in Dazed and Confused, is known for his dedication to his craft. The 44-year-old Texan easily vanishes into whatever role he plays, whether it’s a criminal defense lawyer operating his practice out of a Lincoln Town car in The Lincoln Lawyer, a police officer moonlighting as a contract killer in Killer Joe, a strip bar owner who clashes with his star stripper in Magic Mike, or an overconfident, eccentric and jaded stockbroker in The Wolf of Wall Street.
