I think he was funny on the original SNL back in the 1970’s. Only two movies really were funny with him, at least to me, “Spies Like Us”, and “Trading Places”. He was funny then.
Poor Dan had visions of lots of money from the current Ghostbusters. I be he had a back end deal as a consultant, or something like that and now this film will be a financial failure.
The cast was just not very good and everything could have been better.
So old Dan is lashing out and saying crap that he knows is fiction.
Trading Places is a good movie. But I never liked him.
