It's a nice film and I'd like to watch it again. I think it is from the early 2000's. In English language. Not animated. Probably American. These are some scenes which I vaguely remember:
- People able to move very fast (probably with a device or medicine). When in this state, their bodies are glowing. Human eyes cannnot see them.
- There's a scene in which a man/woman is watering plant with a hose. Someone then activates the lightspeed state and the water drops move very slowly (almost stopped in midair).
- There's also a more advanced lightspeed state. In this more advanced state, the user's body glows even more and they're able to move through solid objects.
