Brian's Song got him there. The 1971 TV movie about cancer-stricken Chicago Bears running back Brian Piccolo pulled a 48% audience share, the most-watched made-for-TV movie at that point, and earned Caan an Emmy nomination. Coppola had already noticed him, having worked together on The Rain People. When The Godfather was casting, Caan was slated for Michael, but he and Coppola pushed the swap to Sonny instead. Good trade. Sonny Corleone's volatility suited Caan in ways Michael's cool calculation never would have, and the Oscar nomination for Best Supporting Actor proved it.
For five years between 1982 and 1987, James Caan didn't make a single film. His sister died of leukemia in 1981. Cocaine came next, and what he described as Hollywood burnout finished the job. Coppola pulled him back with Gardens of Stone in 1987, and Misery opposite Kathy Bates in 1990 proved he could still command a screen. Elf (2003) introduced him to a generation that had never seen The Godfather. He never fully escaped Sonny's shadow, but he didn't seem particularly bothered by it.
He spent nine years on the pro rodeo circuit, competing in team roping after stumbling into it on location for The Rain People in 1968. The karate credentials are equally real: 6th Dan, Master of Gosoku Ryu. During his 1980s hiatus, he coached his son Scott's Little League team and called it the 'high point of my low point.' He briefly lived at the Playboy Mansion in the 1970s during a rough patch, and Hefner reportedly didn't want him to leave.
Al Pacino called him 'my fictional brother and my lifelong friend' in a statement issued after his death. Francis Ford Coppola said Caan 'stretched through my life longer and closer than any motion picture figure I've ever known.' Rob Reiner, Robert De Niro, and Kathy Bates were among the co-stars who paid tribute. His final film, Fast Charlie with Pierce Brosnan, was released posthumously in 2023.
