Hi, Mom! (1970)

Aspiring adult film-maker Jon Rubin (Robert De Niro, Taxi Driver) returns from a tour of Vietnam and, armed with his film camera, attempts to find meaning and inspiration in the counter-culture of New York in 1970. Rubin graduates from surreptitiously filming his neighbours, to joining a militant Black experimental theatre group, before flirting with full-scale domestic terrorism, in this hilariously madcap satire that has still retained its outrageous power to shock, fifty years after initially stunning American audiences.
