Withnail and I is a 1987 British black comedy film written and directed by Bruce Robinson. Loosely based on Robinson's life in London in the late 1960s, the plot follows two unemployed actors, Withnail and "I" who share a flat in Camden Town in 1969. Needing a holiday, they obtain the key to a country cottage in the Lake District belonging to Withnail's eccentric uncle Monty and drive there. The weekend holiday proves less recuperative than they expected.
