Jack does the same cigarette flip into the mouth that Jean-Pierre Léaud practices while sitting in a small Parisian café. Marion then starts a conversation with her ex-boyfriend about whether he is still writing for a political magazine, similar to the café scene in "Masculin Féminin".
Jack makes Marion do an impression of Marlon Brando underneath a bridge in Paris featured near the start of Bernardo Bertolucci's "Last Tango In Paris".
Jack (from "2 Days In Paris") states he wants to see Jim Morrison's grave at Pére-Lachaise because "I'm a huge Val Kilmer fan". Val Kilmer played Jim Morrison in the Oliver Stone's film "The Doors".
