This is Denis Villeneuve’s bizarre short film from 2008, Next Floor.
It won the Best Short Film Prize at Cannes.
Fantastic sound design and visuals, the shot of the chandelier in the finale is great! Thematically i think it (not so subtly) has a stab at mankind’s tendency to lean towards blind gluttony. Possibly it serves as a cautionary tale: don’t enter staring competitions with very serious looking bald waiters.
I would not recommend it to vegetarians, but oddly, would to vegans.
