David Moscow made a memorable big screen debut in the 1988 hit comedy "Big"; his affability, awkward charm and dark curls made him a perfect choice to play young Josh, Tom Hanks' character before his overnight transformation. While his role was relatively brief, he proved an endearing screen presence and served as inspiration for Hanks' performance. That same year Moscow appeared in "The Wizard of Loneliness", a World War II-set drama starring Lukas Haas. The New York native was previously featured on television with a 1986-1987 recurring role on "Kate & Allie" (CBS) as Eugene, a friend of Allie's young son Chip. Moscow returned to television in 1989, with regular roles in two series that met a quick demise. In CBS' "Live-In", he starred as the youngest son in a family who hires a beautiful Australian live-in housekeeper for whom his older brother (Chris Young) falls. Not long after that sitcom left the airwaves, he was cast in "Living Dolls", a spin-off of ABC's successful "Who's the Boss?", about young models. Moscow had a co-starring role in this short-lived series as the mischievous teenaged son of the models' motherly agent (Michael Learned). In 1992, he had a featured role in the Disney feature musical "Newsies", chronicling the newsboy strike of 1899. Moscow virtually disappeared from the scene until 1997 when he was featured as a drug dealer in "Hurricane Streets" and had a starring role in the little-seen touching drama "River Red", playing a young man who takes the fall when his older brother (Tom Everett Scott) kills their abusive father. He next appeared in the 1998 film "Restaurant", a story of metropolitan creative types working in a Hoboken restaurant, playing the childhood friend of Adrien Brody. 1999 saw the actor return to television, in The WB's New York City-set teen comedy "Zoe, Duncan, Jack & Jane". As Duncan, the least sophisticated and most endearing of the group, Moscow reached a level of visibility he hadn't hit since his "Big" debut.
