Absorbing adaptation of Jean Genet's play has three convicts locked in a cell and battling for status. Forest is the king of the cell because he is a murderer awaiting the guillotine. Nimoy is a petty thief constantly bickering with Mazursky, a homosexual prisoner. (Mazursky became a
writer-director.) Finally, Nimoy strangles Mazursky in an attempt to gain new stature in the eyes of Forest. Excellent black-and-white photography keeps the single-cell set consistently interesting, and fine performances are given by all three actors.
