Lookalikes: Damon & Wahlberg

Stand Matt Damon and Mark Wahlberg side by side and you will easily tell them apart. Damon is taller, and they don't have more than a passing facial resemblance. But when you're watching an all-American action movie, it's hard to remember who's pointing the gun, Damon or Whalberg?

Matt Damon

Damon bio: Born October 8, 1970 in Cambridge, Massachusetts. He first met his close friend Ben Affleck at the age of 10, when they loved two blocks from each other. Damon attended Harvard University from 1988 to 1992 but did not graduate.

Damon's best movies: Good Will Hunting (1997); True Grit (2010); The Bourne Ultimatum (2007); Inside Job (2010); Teenage Paparazzo (2010).

Damon's worst movies: All The Pretty Horses (2000); The Legend of Bagger Vance (2000); The Majestic (2001); The Third Wheel (2002).

Critic's view: Variety writes of Damon's role in Good Will Hunting, Towering performance by Matt Damon as a troubled working class who needs to address his creative genius elevates this drama way above its therapeutic approach, resulting in a zeitgeist film that may touch chord with young viewers the way The Graduate did.

Did you know?: Matt Damon and his childhood friend Ben Affleck starred in and co-wrote Good Will Hunting. Affleck is another of our lookalikes. We say he could be Paul Rudd's twin brother.

Mark Wahlberg

Wahlberg bio: Born June 5, 1971 in Dorchester, Massachusetts. As a young man, Wahlberg blinded a Vietnamese man in one eye and was charged with attempted murder. He pleaded guilty to assault and was sentenced to two years in jail at Boston's Deer Island House of Correction. He served 45 days. He was known as Marky Mark in his early years as a rapper.

Wahlberg's best movies: Boogie Nights (1997); Three Kings (1999); The Departed (2006); The Fighter (2010);

Wahlberg's worst movies: Renaissance Man (1994); The Truth About Charlie (2002); Max Payne (2008).

Critic's view: The London Evening Standard writes of Wahlberg's role as boxer Mickey Ward in The Fighter, Wahlberg, always so physically solid, is deep inside himself in this role. His shrouded little eyes never give much away, even when his face is filmed pore-close. He's quiet and contained, a rock: a beautiful man, in a puggy, pugnacious way.

Armand Whyte's view: Superficially, Damon and Wahlberg are alike because they often play such similar roles: quiet action heroes who don't do much on-screen sex. But if we remember that Wahlberg is always a blue collar hero, whereas Damon plays intelligent, even intellectual, types you should be able to keep them apart.
