During the party scene in the film several of the crew appear as extras. Sam (writer/director) in a teddy bear onesie, Saul and Danielle (producers) in jungle outfits, Steven (editor) in a gorilla suit and Ryan (production designer) in an explorer outfit.
Actor Paul Blenheim (Darren) only met Celeste Markwell (Jamie) out of the cast, since almost all of his scenes were filmed separately.
