J-Men Forever, originally titled "The Secret World War", is a 1979 comedy film by Philip Proctor and Peter Bergman of the Firesign Theatre.

They appear in period-style black and white sequences that are used to frame the re-dubbed clips of car chases, explosions, flying men, sinister villains and villainesses, fights, and various other perils that are strung together in a somewhat incoherent plot.

The Bug's first victims are square record moguls Lawrence Milk and Jive Davis, who are hypnotized or otherwise prodded into killing themselves, and bandleader 'Screen' Dorsey, whose car is booby trapped and then run off a cliff.

After he stops choking, The Chief points out that J-Men are flexible enough to survive any life-threatening situation, and the final clips (from the following week's edition of the serial) show exactly how each J-Man escaped their particular peril.

The film did not get notice during its theatrical run, but two years afterwards was popular enough when it was brought up by International Harmony head Stuart Shapiro on the USA Network show Night Flight to the point of a cult following.
