ET Throwback: The 1984 'Ghostbusters' Premiere

Who ya gonna call? Thirty years ago on June 8, 1984, Ghostbusters opened in theaters nationwide and became an instant classic. In celebration, we've got vintage red-carpet footage from when ET was front and center at the film's opening day premiere in Hollywood, with Bill Murray, Dan Aykroyd and Rick Moranis in attendance. Watch the fun reactions as we ask the stars -- including Sylvester Stallone and Richard Pryor -- if they believe in ghosts!
