It took a full year for Supervising Director, Dominic Bianchi & Animation Stunt Performer, Joe Vaux to create the fight sequence between Herbert & Franz.
There are three clocks on the wall above the couch when Franz offers one but later the clocks are gone and replaced with three landscape photos.
For a moment, during the fight between Herbert and Franz, the glass of water on the side table vanishes.
