Weinger was Jewish parents Babs Weinger, a teacher, and Elliott Weinger, an orthopedic surgeon. The eldest of four children, Scott has two brothers and one sister. He spent the majority of his formative years in southern Florida, then moved with his family to Los Angeles when his career began to take off.
Weinger first became interested in acting in the third grade, when an actor gave a presentation for Career Day. He relentlessly pestered his parents to get him an agent until they finally realized that their son was serious about becoming an actor.
His first big role came when he was cast as Steven "Steve" Hale in the sitcom Full House from 1993 to 1995. (It was during the run of Full House that Scott would earn his first motion picture role.)
In later years, his dream of becoming a screenwriter finally came true with his first writing credit, for the WB television show, Like Family, described as a "multi-ethnic crossover comedy about two very different families coming together under one roof." More recently, he received a credit as a co-writer for another WB sitcom, What I Like About You.
Weinger was cast as the speaking voice of Aladdin, the street urchin in the Disney animated feature film, Aladdin (he briefly attempted the singing parts, but gave up that role to Brad Kane). He would reprise the role for the Disney Channel Aladdin series and in two direct-to-video sequels: The Return of Jafar and Aladdin and the King of Thieves.
In autumn of 1994, Weinger left the L. A. scene to fulfill yet another dream: Attending Harvard University. (While attending classes, he continued to work as the voice of Aladdin and made a final appearance on Full House, all while maintaining excellent scores at school. As if that didn't keep him busy enough, Weinger also held a part-time job as a youth correspondent for Good Morning America.)
Scott majored in English and minored in French literature while at Harvard, and graduated magna cum laude in June, 1998. In his first online interview after returning to Los Angeles, he still seemed undecided about his future plans, though he had narrowed down his possibilities writing, directing, acting, and news correspondence.
Since his return to Hollywood, he has starred in a horror film, Shredder; produced an award winning film short, The Cricket Player; and provided his voice for Osamu Tezuka's Metropolis; Disney/Square Co.'s video game, Kingdom Hearts; and the 3-D Disney film, Mickey's Philharmagic
Weinger considers himself to be a writer first, and an actor second.
