show super-fan Al Roker caught up with the stars as they were shooting their cover for Entertainment Weekly magazine
, and while the rest of the cast stayed mum when asked if they knew the movie would be an instant classic, Murray said he thought Ghostbusterswould be a hit

on TV so I thought we had a shot."
