It's been a good year for coming out of the woodwork: Earlier this month, the sorely missed cartoonist Bill Watterson, who stopped writing Calvin and Hobbes in 1995, shocked the comics world when he showed up as a guest artist in the strip Pearls Before Swine. (The creator of that strip, Stephan Pastis, compared the unexpected Watterson collaboration to getting "a glimpse of Bigfoot.") In May, the mostly retired Phil Collins shocked the crowd at a Miami school when he strolled onstage during a student performance and performed "In the Air Tonight" and "Land of Confusion" with the underage musicians; it was his first public "concert" since 2010. Journey's Steve Perry recently came out of self-imposed exile to sing with the band Eels in St. Paul, Minnesota, Washington D.C. and L.A., saying, "I've done the 20-year hermit thing, and it's overrated."
And then there's Dave Chappelle, who's spent the intervening years since leaving his show in 2005 popping up sporadically to do shows and impromptu stand-up sets here and there before announcing a nine-date residency at Radio City Music Hall, starting June 18th. (His explanation on Letterman for his comic wandering: "I never quit, I'm seven years late for work.") Not every artist who's taken an extended professional break or straight-up walked away from a successful career, however, has returned to the spotlight. Here are 10 prominent figures — writers, actors, filmmakers, and musicians — who've taken an extended powder, more or less, from public life. By James Sullivan
