A member of the CityKids Repertory, Mihok made his TV debut in "CityKids", a 1992 "ABC Saturday Morning Special". A Jim Henson production stressing communication and tolerance, it featured a multi-ethnic group of teenage actors as well as Muppets. The young actor also appeared in guest spots on the NYC-filmed dramas "New York Undercover" (Fox, 1994) and "Law & Order" (NBC, 1995). This tall, muscular redhead's imposing look was often counteracted by his sensitive portrayals; he received particularly strong reviews for his role as a mentally-unbalanced young man in the CBS TV-movie thriller "Murderous Intent" (1995). Mihok was a featured regular on the CBS sitcom "Pearl" (1996-97), starring as Rhea Pearlman's rebellious son Joey. With a fine turn in this comedic role, he easily pulled off the character's tough Pearlman-esque attitude, making him believable as her son, although his size and coloring were completely in contrast to the petite brunette's. The actor had a 1999 recurring role on The WB's college drama "Felicity" as Lynn, a competitive swimmer attending the fictional University of New York. While initially seeming to be little more than a loutish jock, his character later proved himself, helping regular Julie (Amy Jo Johnson) tune her guitar, encouraging the apprehensive musician and giving her confidence to perform.

Mihok made his starring film debut in the 1994 racially-themed independent feature "Black Is White". An appearance in Barry Levinson's hard-hitting "Sleepers" (both 1996), followed. While Mihok's performances in both of these New York-filmed features were strong, he first gained real notice with his featured role in Baz Luhrmann's modern take on "William Shakespeare's Romeo and Juliet" (also 1996). Sporting a crew cut and decked out in an open Hawaiian shirt, Mihok played Benvolio, of the Montague ilk, standing alongside Jamie Kennedy's Sampson, Harold Perrineau's Mercutio and Leonardo DiCaprio's Romeo. His work as the amicable and sympathetic Benvolio won the actor a small fan following. After his memorable performance in "The Thin Red Line", Mihok was featured in "Whiteboys" (1999), playing one of a gang of Iowa teens who adopt the stereotypical gangster rapper lifestyle. "Telling You", an independent feature lensed in 1997, starred Mihok as Dennis Nolan, a recent college graduate who finds himself working at a pizzeria in his New Jersey hometown. The film also featured Peter Facinelli (with whom Mihok had previously guested in an episode of "Law & Order), Jennifer Love Hewitt and Matthew Lillard.
