Dumb Mulholland Drive. Even more gleefully artificial than I Saw the TV Glow, its length allows more emphasis and repetition than is really needed – I keep remembering how much Body Melt accomplished in 80 minutes, while after all the buildup, only a couple bodies melt in this one.
After Demi is fired from a TV network for being too old, she gets the inside scoop on the substance, which creates a younger you from the current you, and the two yous alternate weeks of consciousness. Her first day as Qualley she gets her old job back from squishy boss Dennis Quaid, then Demi wastes her own weeks eating junk food in her apartment, then the second week she starts stealing extra youth time, which causes Demi to age rapidly/erratically. It’s a huge problem that neither of them has self control. They start videodroming (Q pulls a chicken leg out of her bellybutton) then body-melting (Q gets the idea to substance herself, then drops a boob out her eyehole on live TV).
