Some actors just seem like two peas in a pod - more than doppelgangers, with something downright chemical connecting them. That's how Matthew McConaughey and Woody Harrelson are often viewed - and it's thanks in no small part to McConaughey's own mother and her fondness for humorous rumors. McConaughey spoke on Tuesday's episode of Access Daily about the popular belief that he and Harrelson are connected by blood as siblings. The Lincoln Lawyer actor was asked what his mother thinks about the rumor calling the two men half-brothers - only to reveal she's fueled it!

Visually, Harrelson, 62, and McConaughey, 53, resemble one another so much that sometimes, McConaughey revealed, their families look at pictures of them and can't tell the difference. But on a deeper level, they have been close friends for years. In fact, the chance to work with Harrelson was a significant factor in persuading McConaughey to take a prominent role in True Detective. Harrelson, likewise, once told Stephen Colbert on an episode of The Late Show, "The year of birth, nine months before, she was on a sabbatical from her relationship with his supposed father, Jim."
