“He was the nicest guy.” The documentary biography “I Am Paul Walker” (8 p.m., Paramount) doesn’t offer terribly deep insights into the child actor-turned-screen heartthrob and action star of “The Fast and the Furious” movies. But it does offer an impressive number of clips and interviews from Walker’s colleagues, friends and family.

We get to see plenty of moments from his early work as a child actor in dog food commercials and appearances in family fare like Michael Landon’s “Highway to Heaven.”

Rich on career details about Walker’s move from eye candy in such movies as “Varsity Blues” to the action sequences of “The Fast and the Furious,” “I Am” has a harder time finding a great deal of conflict or complexity in his private life. He’s praised as a loyal friend and a good brother and someone who’d contribute to charities anonymously and would much rather be in the wild than on a Hollywood soundstage.

Ultimately, he emerges as an impossibly good-looking and confident young man who died too young at a time when his career was defined as “fast and furious.” Fans looking for a defining Paul Walker portrait will have to wait.
