The film described as a "lost" $2.5M effort by Billy Wilder.
The falling man on Myst apears on Waking Life
When the main character walks into the convenience store where the store employee is the same man who was driving the boat car earlier in the film, the employee is wearing a uniform with a "Circle A" logo, the same as the logo for the Circle A convenience store where the main characters in SubUrbia spent most of their time.

The characters were featured not only in "Before Sunrise", but also "Waking Life", continuing conversations held in the first film. Also the line spoken by Celine in the boat that "We're just characters in that old lady's dream. She's on her deathbed, fantasizing about her youth." refers to the concept of Waking Life
Rotoscope animation and speech referencing Waking Life director Richard Linklater
