Disney's live action of The 3 musketeers.

it's definitely a classic comedy... and if you're into reading classics, it's based on le trois mousquetaires, by Dumas. well. as based-on as anything dinsey does; but one thing they absolutely did capture was Dumas's ridiculousness (which itself, as putatitively historical fiction, may have captured the ridiculousness of certain classes of people- namely politicians like the Cardinal, royalty like the king, and the people who fought for them.)

In the books, though, D'Artagnian has to serve 2 years in another military outfit and- perhaps ironically- the king places him in the cardinal's guards just on the advent of war. (A war, which see's our 3 musketeers and D'artagnian having lunch in no-man's land as they lay siege to an english castle. Over a bet.)
