For those who enjoy dark comedy, it's hard to see how anything could be funnier than "Arsenic and Old Lace". With Cary Grant's talent for madcap comedy, with hilariously sinister performances by Raymond Massey and Peter Lorre, with two adorable old ladies who have a very dark secret, plus half-a-dozen other eccentric characters, all involved in a complicated and unpredictable plot, this is a comic masterpiece. Director Frank Capra keeps everything moving and adds his own touch, keeping some dark material entirely light-hearted.

This is the kind of movie for which mere analysis cannot do justice to how well everything fits together. The characters, cast, and writing are all perfect, and the crazy story gives every character some great moments. There is plenty of witty dialogue, lots of funny slapstick and physical humor, and quite a few wild plot developments. None of it is meant to be plausible, but it is all hugely entertaining, and done with such skill that it is easy to suspend disbelief. If you happen not to have seen this before, stick with it for the first few minutes, until you arrive at the home of Cary Grant's two aunts, and then things will take off quickly.

If you enjoy morbid humor, "Arsenic and Old Lace" is an absolute must-see.
