Rick Moranis?

Yeah he played Morty King,no he wasnt the photographer.Do u remember when Brewster see's all those people at the hotel who are trying to get him to buy icebergs and place bets etc?...well Morty King is the little guy with a beard who copies everything Brewster says.Hope this helps.

Rick Moranis had a small part in the film as Monty King, a man who just repeated everything that was said. He appears in the sequence involving the iceberg stock-look for the bearded man in the loud tux.
