If Fosse's own semi-autobiographical film "All That Jazz" (about the meltdown of a chain smoking, Dexedrine-popping, workaholic choreographer/director named Joe Gideon) didn't do enough to whet the proverbial appetite of theatre-lovers everywhere eager to learn more about the mysterious legend, then this film might do the trick.
For a taste of the complexity of Fosse's character and his obsession with his craft, take a look at this great interview Fosse did with David Sheehan around the time "All That Jazz" came out.
Looks like I just may need to start subscribing to HBO again.
