Gabriel earned his first animator credit on a short, "Fun with Mr. Future" (1982), which utilized new animation and live-action stock footage to speculate on future family life. He received his first feature animator credit on the lavish but uneven "The Black Cauldron" (1985) and advanced to character animator on "The Great Mouse Detective" (1986). Gabriel designed the canine and feline supporting players in this charming feature that was hailed as a return to form for the Disney animation department. He wore many hats on the mildly diverting "Oliver & Co." (1988), a musical animal cartoon take on Dickens' "Oliver Twist", serving as one of the storymen, character designers and supervising animators.
Gabriel made his feature directing debut co-directing the cartoon sequel "The Rescuers Down Under" (1990). Though a commercial disappointment compared to the animated musical blockbusters that immediately preceded and followed it, the straightforward adventure tale was notable as the first Disney feature to use the digital post-production technology (known as CAPS). This process allowed for unusual camera positioning and a wider array of art direction options. Shortly after finishing this project, Gabriel pitched the idea that would become his most high profile directing assignment--"Pocahontas" (1995). Working with co-director Eric Goldberg, he managed to craft a distinctively Disney-styled entertainment that presented a complex historical situation while still serving up catchy tunes and cute critters.
