Lol, the first thing I thought of when I saw it was, "Really?!!! Oh, right... directors and screenwriters are most definitely NOT flashaholics. To THEM, it's a cool, futuristic looking light". Same reaction I had when Neo pulled out a Mini Disc in The Matrix as a futuristic data storage component. I LOL'ed thinking to myself, "What? Is he selling pirated music?".
The TK45 would be like a cutting edge, state of the art scientific expedition right now using those shiny ribbed metal 2C flashlights from the 1930's that are barely brighter than a Solitaire.
80-90 years from now, I'd expect a light the size of a Streamlight Nano with the output of a TK70, but then the movie would lose that atmospheric 'what's out there in the dark' sense of drama with cutting edge illumination turning the darkness to daylight.
I sure hope they discover the anti aging pill, not the least because I'd love to see flashlight (and other) tech at the turn of the next millennium. Probably won't even be using LEDs by then.
