Jumping from movie to movie, Jon tried out for another one called Airborne, but didn't get the role. So slowing down a bit, Jon decided to double up on his school courses, graduating a year earlier in 1992 from the valley Professional School. He also was placed up in the "Who's who among American High School Students."
Doubling his courses allowed him to star in seaQuest as the smart teenager Lucas Wolenczak, which began mid-way through 1993. This role was and still is probably the most prominent career choice he made.
Starring in seaQuest for not only one, but two seasons, he has gained immense popularity around the world, appearing more times on the cover of US fan magazines that any other actor ever!
However, during the break from seaQuest DSV, Jonathan visited the Czech Republic, where he was to star in the TV/Family movie "The Good King." In this movie, Jonathan plays the part of "Prince Wenceslas," who is the innocent in all the bad blood in the family.
When the second season of seaQuest returned, Jonathan and Roy Schieder (the star of seaQuest DSV) were asked to host a TV special, "Masters of Illusion: The Wizards of Special Effects." Jon, who wrote a script for the first season (and was not accepted, because seaQuest's first season had been entirely scripted, and Jon wasn't too happy about this). Anyhow, since the second season was pretty much open to suggestions, Jonathan got to have his script performed by the cast (it had to be changed slightly to fit in with the new cast).
During the second season, Jon on another set was the voice of the evil wizard Mozenrath on the Disney Animated TV Series "Aladdin." Says Jonathan about that role: "It's a totally new experience for me," and it certainly was. He was estatic that kids were voicing the kid's characters, and not the older actors. It was extremely different from his seaQuest role. He had to learn how the stand still when speaking his lines. (Apparantely the director had a go at him, because he kept blocking in some actions, which made his mouth keep on bumping into the microphone.)
Jon now stands at 5"10' (178 cm) and weighs 135 pounds (62 kgs).
Apparently he doesn't like doing chores around the house. He's got blue eyes, and dark blond hair, and he's also a terrible morning person, and I quote, "I'm a terrible morning person." (Source - STAR!)
Jon keeps his fitness up by working out at the local Gym in Florida.
Balley's Health Club to be exact.
You'll often find Jonathan relaxing, on the basketball court, or shooting a couple of games of pool or billiards.
At home, his mobile phone is a necessity for him. He's apparantely fallen asleep talking to friends.
