We look at the actor's memorable roles in ''The Client,'' ''Apt Pupil,'' and more

The actor, who died tragically last week, got his first shot at acting when Knoxville, Tenn., police directed a Hollywood casting agent to a scrappy 10-year-old who epitomized the ”lost boy” he’d later portray. A handful of Renfro’s most memorable roles.

The Client (1994)
Plucked from obscurity to star opposite Susan Sarandon in a John Grisham thriller, the actor held his own as a kid witness pursued by Mafia hoods.

Sleepers (1996)
Renfro, playing a young version of Brad Pitt’s character, is one of four boyhood pals who endure hellish treatment from the depraved guards at a juvenile detention center.

Apt Pupil (1998)
Months after his first drug arrest for cocaine and marijuana at age 15, the actor danced with darkness on screen, playing an A student obsessed with a wily Nazi (Ian McKellen) living incognito in his town.

Bully (2001)
Tormented by the neighborhood alpha male (Nick Stahl), Renfro played the reluctant ringleader of a brutal retaliation in this scandalous depiction of actual events.

Ghost World (2001)
A bungled 2000 yacht theft further dimmed his star, but Renfro impressed as the bland but beautfiul store clerk who fascinates Scarlett Johansson and Thora Birch’s sarcastic duo.

The Jacket (2005)
Now eclipsed by his bad-boy persona, the actor embraced it as a fugitive who fuels an amnesiac’s (Adrien Brody) psychological trip in this unusual mind-bender. That fall Renfro was arrested for DUI and later for attempted heroin possession.
