Brewster McCloud (1970)

Bud Cort is the titular character, a young man who lives alone in a fallout shelter beneath the Houston Astrodome whose primary goal in life is to take flight. As Bud prepares himself for his mission, Houston experiences a series of strange murders that all have an inexplicable connection to birds. Typical of many Altman films, there is an expansive cast which includes Sally Kellerman, Shelley Duvall, René Auberjonois, and Margaret Hamilton who finally gets her own ruby slippers. It’s all very expansive and rambly with a lot of details to catch and ponder on while still maintaining a general focus on Cort and his objective.
