BRUCE LEE isn’t an obvious fit for ESPN, beyond the fact lots of people enjoyed his action movies. Yet “Be Water” proves an excellent addition to the network’s lineup of documentaries to fill the sports void, examining the martial-arts star’s legacy and the circuitous, discrimination-marred path he followed to his too-short stardom.

Like a handful of actors and musicians who died young — from James Dean to Marilyn Monroe — Lee’s myth has been fueled by his untimely death at 32, on the cusp of “Enter the Dragon” becoming a huge hit. The movie offered the tantalizing prospect of turning Lee into a star in the United States after the frustration he endured knocking around Hollywood, co-starring in “The Green Hornet” before becoming a martial-arts instructor to the stars.

“Crushed,” as his wife Linda puts it, when he lost out on the lead role in the TV series “Kung Fu,” Lee returned in 1971 to Hong Kong, where he was raised before moving at 18.

Lee had actually been a child actor, and he found an avid audience in a quartet of action movies — including “The Big Boss” and “Fists of Fury” — that paved the way for the elusive victory that came with conquering America. The fact that he didn’t live to relish that moment is itself a tragedy, with the actor suffering a brain hemorrhage after taking medication for migraine headaches.

The documentary expands on Lee’s guru-like status teaching actors like Steve McQueen and James Coburn and basketball legend Kareem Abdul-Jabbar. That, however, proved a recent source of controversy, given the way director Quentin Tarantino depicted him in his fact-and-fantasy mashup “Once Upon a Time in Hollywood.”

Directed by Bao Nguyen, “Be Water” (a maxim Lee used to describe his martial-arts philosophy) employs an interesting tactic, interviewing subjects in voiceover, then showing them at the end. It brings a personal touch to the story — with Lee’s wife, daughter and brother among those featured — while keeping the man himself front and center.

There are also interviews with members of the “Enter the Dragon” team, accompanied by footage of the lines circling the block when the movie opened in Los Angeles.
