So, I taped it, and I just watched it, and ... well, um ... a glass of wine definitely helped.
It was released in 2001, so I guess Jesse would have been in his early twenties when it was filmed (depending on the gap between filming and release). He was playing a 16-year-old. And he looked way too young for the part. He could have passed for twelve. But he had that deep voice, and he was trying to do an American accent (which didn't always work, bless his heart), and I've noticed that a lot of actors tend to drop their pitch when doing foreign accents (compare Hugh Laurie's normal speaking voice to his House voice, for example), so his voice was even deeper. It was kind of funny hearing this really deep voice coming from this kid who looked about twelve.
But I think our boy may have fallen into typecasting along the way. He played the school brain, and in spite of being utterly adorable, none of the girls paid him any attention (until the heroine of the movie noticed him for his brains, of course). He was also a bit of a dork who fumbled socially sometimes. In an odd subplot that didn't seem to have much to do with the rest of the movie, there were father issues, with his father being this incredibly driven ultra-capitalist who didn't approve of his son having a part-time job at some useless place like a bookstore instead of interning at a place where he could get stock options. Then when fighting the evil gargoyles from hell, he ended up teaming up with a priest, had the big breakthrough idea about how to create a lot of holy water, fast, and the priest acted like a kind of surrogate father figure who gave him the approval he didn't get from his father. Gee, does any of that sound familiar?
But the funniest thing was, when I stopped the tape at the end, my TV was set on USA, where an episode of House was just coming on, and it was one of those scenes where Chase is wearing the schoolboy sweater vest look, and I swear, he looked only slightly older than in that movie. I burst into hysterical giggles.
