Luckily Entertainment Tonight was on the scene and documented the festivities. Watch interviews with Bill Murray, Dan Aykroyd, Rick Moranis and reactions from stars -- including Beverly D'Angelo, Rob Lowe, Sylvester Stallone and Richard Pryor -- when asked if they believe in ghosts.

It is hard to believe that it has been 33 years since Ghostbusters first premiered on the silver screen.
