I just watched Futurama: Bender’s Game on DVD. A delightful mixture of many great movies, series and even a board game!
The idea was to spoof Dungeons and Dragons. That the execution of this idea happened to coincide with its creator, Ernest Gary Gygax, is just a… well… coincidence! 
The movie producers have managed to come up with a perfect balance of a the traditional elements of Futurama, a healthy splash of D&D, a dash of Star Trek, a smidge of Star Wars, a pinch of Teletubbies(!), and a [enter your cooking/baking measuring unit here] of 2001: A Space Odyssey. And some other movies and series which I won’t bother to mention here and now…
This combination makes a very entertaining movie, imho the best Futurama movie so far! Looking forward to see whether Futurama: Into the Wild Green Yonder will be able to surpass this one…
