Grégory watches it.

Gérard (Didier Bourdon) watches the show as the word ABSTINENCE is being played.

Carpet is the same as in the spooky hotel.

Heroes have a "3 time counters" clock on the wall.

Grégory uses it as a metaphor for his couple when trying to get Flo back.

When escaping the wine tasting tour, Augustin poses on a ledge with his hood on like in this game.

Hero says "I'm not a babysitter!". The same actor is the hero of "Babysitting".

Official Italian remake

The improvised neon stick fight in the gipsy van is a spoof of The Empire Strikes Back. Also, Greagory tries to use the Force to get his neon stick, like Luke on Hoth.

Grégory spends half the movie trying to imitate the reverse kick in that movie and the final scene is remade near the end.
