The wristwatch Zak finds is actually a top-secret device developed by one of his fathers former students, now working for the high-tech company, Quantum Technologies. The device speeds up the molecules of whoever wears it, thus rendering him invisible. Perhaps more important, the watch also allows Zak and Francesca to have some fun changing things in the world without anyones knowledge. For example, theres the rave scene, with four hundred extras at a DJs dance party.
Its a hip, funny sequence with great special effects, explains producer Julia Pistor. The really fun part is watching the kids help their friend Meeker (Garikayi Mutambirwa). Using the watch, they slip into hypertime to jazz up his scratches and his dance groove, with no one the wiser, including Meeker remember, they cannot be seen while in hypertime.
The fun of being invisible in hypertime can, however, be unexpectedly stopped.
With a device that dispenses liquid nitrogen, people in hypertime can be frozen, thereby slowing down their molecules and bringing them back to real time, explains executive producer Albie Hecht. Zak, Francesca and Dopler create a liquid nitrogen shooter by adapting actual paint guns which they get from Meeker, who works in an extreme sports store. I think its a terrific way to maintain a sense of jeopardy and adventure in the film, and yet not fall back into the easy thing of getting out an AK-47 and blowing away peoples heads. The creation of the adapted paint guns is a good way to bring the technology to a level that any audience can understand instead of shooting paint or bullets, they shoot frozen liquid nitrogen.
Jesse Bradford relished his special effects scenes in the film.
Were doing some really cool shots like they did in The Matrix and Charlies Angels, says Bradford. Theres a camera moving around us in the middle of a stunt as were leaping or kicking.
Visual effects supervisor Michael Fink recalls one scene in particular that requires Bradford to dive for a valve.
