Today, 35 years ago, this classic movie was released.
A comedy - set in New York City - about a ghost catching business.
With four failed and eccentric academics - grabbling with slimy extra-terrestrial type creatures.
Ground breaking and successful, it grossed $300 million - on a $30 million budget.
Both were, at the time, unprecedented figures for a comedy movie.
Nominated for two Oscars, and the first movie to link humour to science fiction.
