Shaft's Big Score (1972)
Shaft's Big Score! is a 1972 action film directed by Gordon Parks. It is the second entry in the trilogy starring Richard Roundtree as the private detective John Shaft. Ernest Tidyman once more supplied the screenplay. The first film's composer Isaac Hayes was unavailable, so Parks, the returning director, did the score himself. The film was produced on a budget of $1,978,000.
