10 Actors Who Changed Their Entire Image In One Movie

10. Matthew McConaughey - Dallas Buyer's Club

Matthew McConaughey in recent years has become one of the biggest A-listers in Hollywood with smash hit performances and huge box office successes. However, many people still remember him as the rom-com slick man that gathered him fame in the 2000s.

McConaughey began his time as a character actor, playing the unusual side characters in indie movies until he found mainstream success in rom-coms, where he often played the charming yet cocky leading man who finally gets locked down.

Movies such as The Wedding Planner, How to Lose a Guy in 10 Days, Failure to Launch, Fool's Gold, and Ghosts of Girlfriends Past filled his filmography. But it wasn't until Dallas Buyers Club that McConaughey launched to super-stardom.

In Dallas Buyers Club, McConaughey lost 50 pounds to play a man with HIV and delivered an amazing performance that became a modern classic. In one role, McConaughey shredded his typical, muscle-bound image and won an Oscar for his extremely emotional, nuanced and enthralling performance.

His roles suddenly changed in Hollywood and now he is an intense lead actor who smashes the box office and awards nominations with almost every movie.
