CRITICS’PICKS

“Shampoo,” made in 1975 but set in 1968, the night before Richard Nixon’s election to the presidency, was directed by Hal Ashby and written by Robert Towne and Warren Beatty, who may have produced one of the best scripts in the last three decades. The film, showing Saturday as part of the Hollywood Forever Cemetery’s Cinespia summer screenings, stars Beatty as a Beverly Hills hairdresser whose active and complicated sexual life leads him to disappointment as the country slides into a long cultural hangover and era of political turpitude.
