I spent much of the mid-90's secretly fascinated by JTT. I would tape Home Improvement to watch after work and although I have a tendency to like younger men you'll be pleased to know that in this case I just thought he was a fantastic actor. I loved Randy's dryness, his sense of humour and his facial expressions. I can still watch Home Improvement and feel the same awe for JTT. He was only 10 years old when he started on the show and he became a firm favourite with the tweenys of the era.
Then with the world at his feet - JTT all but disappeared. A couple of movies followed and he was the voice of Simba in the Lion King but save for a few guest stints on random TV shows (notably Veronica Mars), all has been quiet on his career front.
It turns out Jonathan went off to Harvard and now attends Columbia University. Little has been heard of him lately and in fact there are dozens of posts dedicated to the question - 'Where Is Jonathan Taylor Thomas?' Hopefully he will return to acting as I for one miss him.
