Leonard continued his acting career, landing roles in "Bluffing It" (1987) and "My Best Friend Is a Vampire" (1987). His next role was in "Dead Poets Society" (1989),opposite Robin Williams and Ethan Hawke, where he played the character of Neil Perry, a young student whose passion for acting is smothered in fear of his father's wrath.

In the same year, Leonard took a smaller role in Martin Scorsese's "The Age of Innocence" (1993),starring Daniel Day-Lewis, Winona Ryder, and Michelle Pfeiffer.
