A former model and commercial actor who utilized his working-class ethnic good looks for comedic effect in several sitcoms, LeBlanc began his professional career in commercials for Heinz Ketchup, Levi's Jeans and Doritos. He entered series TV with the high school drama, "TV 101" (CBS, 1988-89) and appeared in sitcom guest spots before co-starring, opposite Joseph Bologna, in the "Married With Children" spin-off "Top of the Heap" (Fox, 1990-91). As Vinnie, the younger half of a blue-collar father-son team that attempted to prey on rich women, LeBlanc demonstrated that he could smile, wear tight jeans and act dim-witted. After that short-lived gig, he reprised the role for another failed effort, "Vinnie and Bobby" (Fox, 1991-92).

LeBlanc finally struck sitcom gold as part of the twentysomething ensemble series, "Friends" (NBC, 1994- ), as aspiring actor Joey Tribiani. The beefy actor provided enough charm and wit to his character to elevate what could have been just another "himbo" role. He has also appeared in more serious TV projects including "Anything to Survive" (ABC, 1990), a telefilm co-starring Robert Conrad, and two feature-length installments of Showtime's stylish "Rebel Highway" (1994) series: the John Milius-directed "Motorcycle Gang" and "Reform School Girl", helmed by Jonathan Kaplan. The former was a "family against nature" tale while the latter two were zesty remakes of two 1957 American International Pictures drive-in flicks. His feature debut, "Ed" (1996), in which he played straight man to a chimp, however, failed to win over critics and audiences. LeBlanc fared somewhat better with his turn as Major Don West in the feature version of the 60s TV series "Lost in Space" (1998). In 2002, LeBlanc began filming for "Charlie's Angels 2" and challenged his beefy boy image in his starring turn as O'Rourke in the war comedy "All The Queen's Men," in which he is asked to cross enemy lines while cross-dressed in order to infiltrate a factory which exclusively employs women.
