The Hole (1962)
The Hole is a 1962 short animation by John Hubley and Faith Hubley
that won an Academy Award for Short Subjects (Cartoons) in 1962.
The film uses improvised dialogue from Dizzy Gillespie and George Mathews
as a pair of construction workers, one white, one black.
Working deep underground, our cartoon heroes begin debating the fate of the world
and the possibility of nuclear annihilation … from under the streets of New York.
