Dagomir,
Congratulations for a very imaginative video! You nicely recreated a retro film noir ambiance in the intro movie, and Vlatko's explanation at the end was very clear --- clever use of a clear board makes it even cooler! That said, the intro movie was perhaps a bit long (as already mentioned by another reviewer), and it would have been nice if the defusing of the bomb in the intro movie had been a little bit more explicit: perhaps Vlatko could have brought the suitcase to a dark room and drilled holes in it, to eliminate the risk that photons from the streetlights would trigger it. Also, at the very end of the video, during Vlatko's explanation, it would have been a nice plus if a schematic of the 5 beam splitter / 10 mirrors setup could have been shown... But of course these are little details: overall, yours is a very strong entry. You nicely illustrated the fun and coolness of quantum mechanics, and I predict your video will do very well in this contest! Good luck!

P.S. Compared to the regular FQXi essay contests, the video creators seem to be reluctant to rate each other's videos, and, as you may have noticed, it looks like very few videos will get to the 10 community votes threshold needed to be even considered for the final round (if you are not already a FQXi member). If you have the time to take a look at my trilogy of videos "This Is Physics", where I try to convey the "fun of physics" by focusing on some of the greatest moments of its history, it would be quite appreciated!
