Film critic Roger Ebert once called “Beyond the Valley of the Dolls,” Russ Meyer’s 1970 cult hit, a movie that “seems more and more like a movie that got made by accident when the lunatics took over the asylum.” Meyer was a director of X-rated films (“Vixen!”), after a string of edgy, titillating cult hits Faster, Pussycat! Kill!. [...] yet 20th Century Fox handed him the keys to make a satire of one of the studio’s biggest recent hits, Mark Robson’s “Valley of the Dolls.” What Meyer came up with was a mash-up of satire, sex, music, melodrama and a free spirit that captured the zeitgeist of the times.
