Mark Hamill "Totally Forgot" His Cameo in Stephen King's 'Sleepwalkers'

You'd be forgiven if you don't remember Mark Hamill's brief appearance in one of Stephen King's most critically panned movies, because he doesn't remember it either. At least, that's according to The Long Walk star, who had much meatier roles in Mike Flanagan's The Life of Chuck, and in director Francis Lawrence's new film that's set to release in September courtesy of Columbia Pictures.
