One of the true cult classics. He's a 19 year-old kid obsessed with death, suicide, and the afterlife. She's an 80 year-old woman that "loves life." They meet at a funeral, and their adventures together begin. It's not quite a romance, not quite a buddy picture. It is, however, one of the '70s quirkiest comedies, and its bleak morbidity is uncommonly matched by its over-the-top hilarity. Bud Cort would soon become a cult icon for the next 30 years (and going).
It's hard to imagine a more scattered and absurd film, and Britannia Hospital must be a lot of fun if your mood has been chemically altered. Before the day is up at the kooky Britannia Hospital, there will be a mad scientist who not only creates a synthetic, talking brain but also hacks up Malcolm McDowell with a meat cleaver, there'll be protests, a labor strike, and the Queen of England will be on hand to witness it all. Crazy, and pretty much nonsense in the end. Check out The Kingdom TV series for a similar story done with more flair.
