16. Rick Moranis

Ghostbusters is something you can watch without much justification. A great blend of humor, special effects, and sci-fi awesomeness can be found in the timeless 1984 film. Evidently, the upcoming Ghostbusters reboot has stimulated discussion on the original movie, which has led to the discovery of further previously unreported details about its production. 

The most recent was when Rick Moranis completely improvised one of the funniest scenes from Ghostbusters, in which Louis Tully reveals the business and tax information of a couple who have just arrived at his party. Now, Rick Moranis’ performance as Lovis Tully wasn’t precisely scripted. Instead, he completely fabricated the character’s backstory to give him a better depiction within the series.
