Comedy movies with premises that don't sound like comedies.
A few years ago, TCM was showing arsenic and old lace. The presenter described the plot of the movie and iterated that, while it may not sound like a comedy, it is indeed one. This has made me think of whether or not there are other comedies with premises that don't sound like comedies.
Here are some that I thought of. Dr strangelove, weapons, dogma, kind hearts and cornets, an American werewolf in London, fargo, crimes and misdemeanors, four lions, the death of stalin.
