I love 'My Science Project'. I first saw it on HBO one day back in 87 and loved it right away, it's a great sci-fi thriller, with many moments of comedy as well.
It concerns a car nut high school student played by John Stockwell (you'd think that after the hell he went through with Christine, he'd stay the heck away from cars), who needs a science project to pass his science class, problem is, he doesn't have one. So one night he, and his new girlfreind are rumaging around in an old military junk yard outside of town hoping to find something suitable to impress his teacher, and find a very odd little machine. It's high tech looking, with a glass globe mounted in the middle that when powered up, emits electricity that resembles one of those plasma globes you'd find at Spencers Gifts in the mall. As he's cleaning it, he decides to hook it up to a power supply, this turns out to be a huge mistake as 'the gizmo', as it's called in the film, turns out to be an engine from a spacecraft and can locally warp time and space, bringing objects and people from other times into our own. It soon goes wildly out of control and eventually the whole school is caught in a warp, and it's up to Stockwell, and his wise cracking freind, played wonderfully by Fisher Stevens, to shut down the gizmo for good.
A very underrated film, with impressive visuals that still hold up well (except for the dinosaur), great acting from it's cast, inspired writing, and when watched on a good surround set up, a great audio mix to boot. It means no harm, and is fun.
