A Funny Thing Happened on The Way to The Forum (1966)

For this entry I decided to set aside my hatred of Sondheim (Broadway's most repetitive composer) and watch A Funny Thing Happened on the Way to the Forum.  And much to my surprise, I actually kind of enjoyed it.  The score is sort of pleasantly forgettable, and they don't repeat songs too much.  It's loosely based off the work of Plautus.  The main plot revolves around a young man trying to woo the hooker next store with the help of his slave.  It's a farce, so mistaken identities abound, but everything gets sorted out in the end.  As far as historical accuracy goes, they weren't really trying.

Titus (2000)

Titus probably doesn't really belong on this list, but I like it so much I couldn't resist.  It uses the text of William Shakespeare's Titus Andronicus and isn't based on any actual historic event.  It is, however, wonderfully weird and very gory.  The acting is superb.  It takes place simultaneously in ancient Rome and the present, and tells the sad tale of a formerly great man caught in a horrible cycle of revenge, with almost everyone losing in the end.
