The River (1997, Tsai Ming-Liang)

Ann Hui plays the director who casts passer-by Lee as a body floating in the river, after which he starts having serious pain in his neck and back. Running into his dad in a cruisy bathhouse doesn’t help (dad Miao Tien is a Goodbye/Dragon Inn star), while mom (Lu Yi-Ching of Stray Dogs and everything else) deals with water leaking into their apartment. The same three actors play the family in Rebels of the Neon God, so I’ll have to go even further back.
