Dom DeLuise shows up for one scene to lampoon Marlon Brando from The Godfather and Patrick Stewart is on hand to imitate Sean Connery's King Richard from Prince of Thieves . There are so many jokes that it's difficult to pick out anything memorable. Nearly every time we see Prince John, his rather sizeable mole has moved somewhere else. At one point, the Sheriff even feels compelled to mention this. Most of the overblown musical numbers are also fun, with obviously-dubbed singing voices and rappers fulfilling the function of a Greek Chorus.
Parodies are hard to do well, as is shown by the mediocrity of so many recent attempts.
No matter how ripe a genre is for satirizing, unless you know how to do it, there are no guarantees. Fortunately for Men in Tights , Mel Brooks has been doing this kind of thing for decades.
