DON'T MISS: "Showbiz Kids" -- Stardom at a young age can be incredibly exciting -- and often full of pitfalls. This compelling documentary, written and directed by former child actor Alex Winter ("Bill and Ted's Excellent Adventure"), explores the complexities of growing up under the glare of Hollywood's spotlight and does so without shying away from the industry's difficult truths. Among the prominent former child stars sharing their stories are Henry Thomas ("E.T. the Extra-Terrestrial"), Mara Wilson ("Mrs. Doubtfire"), Todd Bridges ("Diff'rent Strokes") Evan Rachel Wood ("Thirteen") and Cameron Boyce, a Disney Channel favorite who died last year, at 20, after suffering an epileptic seizure in his sleep. The film also follows two aspiring young hopefuls as they chase their showbiz dreams. (9 p.m. Tuesday, HBO).
