Ed Wood has been a favorite target of many people as his films while fun were just very inept and all over the place. MST3K slammed a few of his famed films during their run on TV including "Bride of the Monster" and "The Sinister Urge" and the commentary they provided was very funny but for some reason "Plan 9" eluded the guys of MST3K.
Thankfully Rifftrax has brought their brand of commentary and jokes to what has been dubbed "The Worst Film of All Time", Mike Nelson, Bill Corbett and Kevin Murphy take to task making fun of all the obvious mistakes and bad acting in Plan 9, the horrid editing, the terrible day for night or night for day changes from one scene to another and many other problems throughout the movie.
Anyone who has seen the movie on its own knows its funny just as it is, but with the Rifftrax crew its hilarious. The constant jokes about Bela Lugosi, his addictions and the terrible attempt to use a stunt double for Bela through much of the film are some of their best work. I personally enjoyed the Tor Johnson riffs and pop culture references make this one of the best from the guys and its well worth having as this is the perfect type of film that deserves a good harsh riffing.
