Venda D'Abato, who portrays Ajay, was considered for the part of Caroline Winters.
The various scenes of the Innocent Killers doing their jobs at the beginning of the film were shot months apart. A pick up shot from the Joey-Caroline segment was even shot 8 months after principle photography for the saga had been completed.
The joke that Joey attempts to tell to the Beta Hunters is the same joke he tales various times throughout the saga. The complete joke is never heard.
The scene of Ruby James, the Shadowdragon, leaving the bar with the red head is the last scene Demarcus Young filmed for the saga.
The bar scene at the beginning of the film has the most lead characters of any scene in the series where the actors are actually present together. Other scenes through out the series with main characters together are created through trick photography and editing.
