Martin Bregman, the outspoken, notoriously tenacious film producer behind “Scarface,” “Dog Day Afternoon,” “Serpico” and other late-20th-century crime dramas, died on Saturday. He was 92.

The cause was a cerebral hemorrhage, his wife, Cornelia, told the New York television station WNBC. She did not say where he died.

“I have opinions, and I express them,” Mr. Bregman told The New York Times in 1987. “I don’t let the director do whatever he wants. I guess that makes me seem like an anomaly.”

Some of those directors were formidable. The first film Mr. Bregman ever produced was Sidney Lumet’s “Serpico” (1973), the true story of a New York City cop who blew the whistle on police corruption and paid for it dearly. The film was also the beginning of a new kind of relationship with its star, Al Pacino, a former client who was then 33 and fresh from “The Godfather.”
