Reefer Madness: The Movie Musical (2006)

In the vein of Little Shop of Horrors (1986), Reefer Madness: The Movie Musical (2005) is a film version of a musical based on a popular cult film, in this case, 1936's propaganda film Reefer Madness, which demonized weed for generations! A star-studded cast including Kristen Bell, Neve Campbell, Alan Cumming, and Christian Campbell in a hilarious over-the-top parody of the reactionary tone of the original film. Remember that scene in the original where the dude smokes a jay and then plays the piano hella fast? This is like that for 90 minutes. Thankfully both Alan Cumming and Christian Campbell go shirtless in a musical number, with Christian nicely bulging out his undies! And let's not forget the Crypt Keeper himself, John Kassir, sporting a BDSM outfit with a thong in another number!
