James Caan, the curly-haired tough guy known to movie fans as the hotheaded Sonny Corleone of “The Godfather” and to television audiences as both the dying football player in the classic weeper “Brian’s Song” and the casino boss in “Las Vegas,” has died. He was 82.

His manager Matt DelPiano said he died Wednesday. No cause was given and Caan’s family, who requests privacy, said that no further details would be released at this time.

Al Pacino wrote in an emailed statement that, “Jimmy was my fictional brother and my lifelong friend. It’s hard to believe that he won’t be in the world anymore because he was so alive and daring. A great actor, a brilliant director and my dear friend. I loved him, gonna miss him.” Robert De Niro also wrote that he was, “very very sad to hear about Jimmy’s passing.”

A football player at Michigan State University and a practical joker on production sets, Caan was a grinning, handsome performer with an athlete’s swagger and muscular build. He managed a long career despite drug problems, outbursts of temper and minor brushes with the law.

Caan had been a favorite of Francis Ford Coppola since the 1960s, when Coppola cast him for the lead in “Rain People.” He was primed for a featured role in “The Godfather” as Sonny, the No. 1 enforcer and eldest son of Mafia boss Vito Corleone.

Sonny Corleone, a violent and reckless man who conducted many killings, met his own end in one of the most jarring movie scenes in history. Racing to find his sister’s husband, Corleone stops at a toll booth that he discovers is unnervingly empty of customers. Before he can escape he is cut down by a seemingly endless fusillade of machine-gun fire. For decades after, he once said, strangers would approach him on the street and jokingly warn him to stay clear of toll roads.

Caan bonded with Brando, Robert Duvall and other cast members and made it a point to get everyone laughing during an otherwise tense production, sometimes dropping his pants and “mooning” a fellow actor or crew member. Despite Coppola’s fears he had made a flop, the 1972 release was an enormous critical and commercial success and brought supporting actor Oscar nominations for Caan, Duvall and Pacino.

Caan was already a star on television, breaking through in the 1971 TV movie “Brian’s Song,” an emotional drama about Chicago Bears running back Brian Piccolo, who had died of cancer the year before at age 26. It was among the most popular and wrenching TV movies in history and Caan and co-star Billy Dee Williams, who played Piccolo’s teammate and best friend Gale Sayers, were nominated for best actor Emmys.

After “Brian’s Song” and “The Godfather,” he was one of Hollywood’s busiest actors, appearing in “Hide in Plain Sight” (which he also directed), “Funny Lady” (opposite Barbra Streisand), “The Killer Elite” and Neil Simon’s “Chapter Two,” among others. He also made a brief appearance in a flashback sequence in “The Godfather, Part II.”

But by the early 1980s he began to sour on films, though Michael Mann’s 1981 neo-noir heist film “Thief,” in which he played a professional safecracker looking for a way out, is among his most admired films.

Mann said “Jimmy was not just a great actor with total commitment and a venturesome spirit, but he had a vitality in the core of his being that drove everything from his art and friendship to athletics and very good times.”

Caan had begun to struggle with drug use and was devastated by the 1981 leukemia death of his sister, Barbara, who until then had been a guiding force in his career. For much of the 1980s he made no films, telling people he preferred to coach his son Scott’s Little League games. Scott Caan also grew up to be an actor.
