(Editor's note: This column was originally published on April 13, 2018.) Most actors have one definable role in their careers, the one that when people see them standing in a grocery store line they can’t help but remind them of, often a little too loudly. So it’s no surprise some of television's current series regulars and guest stars fall victim to that, especially after appearing on one of the medium’s most durable sitcoms. During its 10-year run on NBC, Friends featured guest appearances by the like of Julia Roberts, Brad Pitt and George Clooney, along with a host of familiar faces and up-and-comers. The series ended its run 14 years ago this coming May, but actors like Steve Zahn, Mark Consuelos, Dermot Mulroney, Kevin Rahm, Sherri Shepherd and many others will forever be known as a Friend of Friends.
