In case you haven't heard of them, the Firesign Theater are 4 or 5 guys from LA who make hilarious, hermetic drug-induced humor. Mostly famous for comedy albums like Don't Crush That Dwarf, Hand Me the Pliers and How Can You Be In Two Place At Once When You're Not Anywhere At All, they also made some movies. J-Men Forever is one of them.
Their technique was to take old Republic serials like Commando Cody and the Copperhead and re-dub them, like Woody Allen's What's Up, Tiger Lily. So we get the story of the evil Lightning Bug, a madman from the Moon who plans to take over America with rock 'n' roll and hash gas. A master of disguises, the Bug can look like almost any villain in a serial. It's up to the J-men to stop him!
The good news: This is pretty funny. The bad news: They did it better in Hot Shorts, which is pretty much unavailable. They re-use some of the shorts, and a few of the jokes from Hot Shorts in J-Men.
So, until you can get Hot Shorts, try this. If you like it, you'll like Hot Shorts better. If you don't, you'll still like Hot Shorts.
In conclusion, contains as an bonus feature a v. low budget interview with George Wallace, the guy who played the original Commando Cody - the Rocketman. Interesting guy - a sailor, a boxer, a lumberjack, a bartender/singer, and once punched in the nose by Clayton Moore, the Lone Ranger.
