Must-see movies are futuristic classics that shouldn't be missed. Of course, not every must-see is perfect. That's why we've rated them 1-5 on the patented "crunchy goodness" scale.
Title: Rocky Horror Picture Show
Vitals: This campy musical became such a cult phenomenon that it's easy to forget that it's also a spot-on satire of 1930s science fiction staples like Frankenstein and Flash Gordon. Dr. Frankenfurter, the "sweet transvestite" of every queer teen's dreams, is a mad scientist from a planet called Transsexual Transylvania who is trying to build a perfect man (Rocky) in his lab. When young newlyweds Brad and Janet stumble upon Frankenfurter's castle, they are swept into a world of time-traveling, planet-hopping, sex-fiending aliens whose otherworldly values change our human heroes forever.
Famous names: Tim Curry, Susan Sarandon, Meatloaf, Ultra Violet
Crunchy goodness: 5
Sight you'll never unsee: Tim Curry as the hottest alien scientist transvestite ever captured on film, strutting around in an sparkly cape right out of Flash Gordon serials, singing: "I'm not much of a man by the light of day, but by night I'm one hell of a lover . . . I'm just a sweet transvestite from Transsexual Transylvania."
Memorable product tie-in: Rocky Horror Picture Show became the first "midnite movie" that includes ritualized audience participation: people shout out lines, dress up to reenact the movie while it plays, dance the Time Warp in the aisles, and squirt water during the rainstorm scene (also, much to the annoyance of generations of movie theater employees, they throw rice during a wedding scene, and toast when Frankenfurter proposes a toast). Midnite shows of Rocky Horror, which have been a staple at indie theaters for over three decades, are probably the movie's most lucrative tie-in, along with sales of rice and water guns in the vicinity of said theaters.
Stunt casting: An in-his-prime Meatloaf chews scenery (and belts out a rock tune) as Frankenfurter's first lab creation, Eddie, whom the scientist put into deep freeze for being disobedient.
