NOW: Wil Wheaton
After leaving the "Next Generation" series in the fifth season, Wil Wheaton went on to enjoy an extremely successful (albeit under-the-radar) career, amassing nearly 100 film and television credits. He has played himself on more than a dozen episodes of "The Big Bang Theory," and recently began hosting his own show entitled "The Wil Wheaton Project." But let's be real — he'll always be the kid from "Stand By Me." —XFINITY Entertainment Staff (Photo: Astrid Stawiarz/Getty)
