Kilner came late to acting having established a successful career as an investment banker managing accounts for Fortune 500 companies. The handsome blond began making appearances on episodic TV in 1989 on such diverse shows as "The Cosby Show" and "China Beach". Kilner had a recurring role on the CBS nighttime soap "Knots Landing" (1989-90) and made a memorable appearance as a gay man fighting his sick lover's parents over visitation rights on a controversial episode of "L.A. Law" (NBC, 1990). He appeared in small roles in "Switch" (1991), "Twenty Bucks" (1993) and "The Stoned Age" (1994). Kilner portrayed the leading man in the first season of the CBS romantic sitcom "Almost Perfect" (1995-96): a workaholic district attorney who tried to juggle his career and a relationship with the equally busy TV producer (Nancy Travis). The show's dialogue was brisk and the attractive leads shared a wonderful onscreen chemistry that raised the level of the sitcom above the norm.
