10 Genius Ways Movies Made You Rewatch Them
3. To Catch Every Sight Gag - Airplane!
Airplane! is one of the funniest films of all time, and while nobody would call its brand of humour subtle, that's entirely the point. In the grand tradition of genre parodies, Airplane! populates almost every single shot with at least something funny - and often, many funny things.
In fact, the frame is often so densely filled with sight gags in both the foreground and background that it's impossible to catch them all on a single viewing. And so, Airplane! and features like it encourage viewers to return for additional helpings not just because they're hilarious, but also because there's so much more hilarity to seek out in the periphery.
Fun fact: a totally scientific study in 2012 claimed Airplane! to be the funniest film ever made, registering an average of three laughs per minute. Though given the sheer density of gags strewn throughout, that's very clearly low-balling it.
