Karlijn Smit who plays Millie and Vincent van Ommen who plays Matthias were both born on 14 June 1982.
The waiter in the restaurant scene with Millie and Matthias is actually the Chef and the owner of the restaurant.
The director and producer were so impressed by Vincent van Ommen's audition tape that they offered him the part without ever meeting him before the shoot.
The Polaroids in the film were actually made when cast and crew went barhopping one night in Amsterdam when still in pre-production.
