Bright began his career doing live television in Manhattan at the age of 18, and made his film debut in Robert Wise's Odds Against Tomorrow (1959). He also worked on several movies early in his career with his friend Sam Peckinpah.
In 1965, Bright starred in poet Michael McClure's two-person show The Beard, performing first in San Francisco and later in Los Angeles, New York City, and London. The play involved simulated sex acts. Bright, the producer Robert Barrow and director Robert Gist were arrested in San Francisco and Los Angeles multiple times on charges of lewdness, before winning a restraining order halting the arrests. In granting the restraining order, the California Supreme Court ruled that the First Amendment protected live theatrical performances.[4][5]
In the book, Neri's character is a former New York City police officer who is hung out to dry by the department after killing a sadistic pimp. Michael uses Corleone family influence to get him off the hook and draws Neri into his service. At the end of the first film, Neri, dressed as a police officer, murders rival mob boss Emilio Barzini and his henchmen during the film's baptism scene. Also, the last faces to be seen in The Godfather are Bright’s and Diane Keaton's, as he closes Michael's office door in her face. Bright also played Neri in both sequels, thus becoming one of five actors to appear in all three Godfather films; his character murders Fredo Corleone (John Cazale) at the end of The Godfather Part II and the Vatican banker Archbishop Gilday at the end of The Godfather Part III.
Bright continued to make a number of both commercial and independent films, such as Jaded (1998). He also continued working on stage and in television, appearing on such shows as Law & Order, Oz, Third Watch, and The Sopranos. These later performances showed Bright using an oxygen tank in all these appearances (although he suffered from emphysema, the tanks were props for the characters).
Bright was struck and killed by the driver of a tour bus on the Upper West Side in Manhattan on February 18, 2006.[1][6][7][8] He was hit by the rear wheel of the bus, and pronounced dead on arrival at Roosevelt Hospital. The driver claimed to have been unaware of the collision until he was notified upon reaching the Port Authorityinmidtown Manhattan, where he was interviewed by police. Ultimately, no criminal charges were filed, though the bus driver's license was suspended for failing to yield the right of way to Bright, who had been in a marked crosswalk with the walk sign on at the time he was struck. Bright was 68 years old, and was survived by his wife Rutanya Alda, son Jeremy, daughter Diane, and brother Charles.
