1. If Tom said "zotz", everything around him went into slow motion,
2. If Tom pointed his finger, it induced a sharp pain (I remember in the class he was teaching that whenever students raised their hands and Tom pointed to them, they grabbed their stomachs in pain), and,
3. If Tom pointed his finger and said "zotz" at the same time, it was a killer.
When he experimented on a fly circling his lamp, he pointed at the fly, the fly dropped, and then got back up and took to the air, circling the lamp again. When Tom said "zotz", the fly was suddenly in slow motion. And when Tom pointed at the fly and said "zotz", the fly dropped for good, dead.
I remember absolutely nothing else about the movie. Yeah, it's funny how some things stick with you for, what?, 40 years.
Sheesh, now I'm thinking I'll check Amazon for the movie.
