Which 1975 film, a satire on the lack of commitment and shallow behavior in California, starred Warren Beatty, Julie Christie, and Goldie Hawn?

Warren Beatty stars as George Roundy, a charismatic and sought-after Beverly Hills hairdresser whose professional life is hopelessly entangled with his romantic one. The film unfolds over a chaotic 24-hour period as George juggles his current girlfriend, played by Goldie Hawn, with his ex-lover, played by Julie Christie. To complicate matters, Christie's character is now the mistress of a wealthy businessman whom George is trying to court for a loan to open his own salon.

Co-written by Beatty and legendary screenwriter Robert Towne, the film is a sharp social satire. It uses George's inability to commit as a lens to critique the sexual politics and emotional vacancy of its wealthy Southern California setting. The entire story is pointedly set on Election Day 1968, the day Richard Nixon was elected president. This backdrop of national political turmoil serves as a stark contrast (Review) to the characters' self-absorbed personal dramas, marking a symbolic end to the free-wheeling attitudes of the 1960s.

A critical and commercial success, the film earned four Academy Award nominations, with Lee Grant winning for Best Supporting Actress for her role as the jilted wife of the aforementioned businessman. It remains a quintessential film of the "New Hollywood" era, remembered for its cynical wit and complex characters.
