Interesting. The Mel Brooks Collection does contain Robin Hood: Men in Tights, but it doesn’t contain Spaceballs or Life Stinks. I mean, I can understand why the set doesn’t include Dracula: Dead and Loving It*, but it is a little odd that it skips those two earlier films — especially since they’re the only other two films Brooks has ever directed. Maybe securing the rights to those two was a problem.
* It’s godawful. I attended a Monty Python Society meeting once, shortly after graduation, where the then president had decided to screen the film. I got there, saw what they were going to watch, and walked right back out the door.
