Corey Haim and Corey Feldman are the only cast members from the The Lost Boys (1987) to return. Jamison Newlander also returned but his scenes were deleted.
Corey Feldman was originally reluctant to re-appear as Edgar Frog but changed his mind when he was offered a larger part in the story.
Towards the beginning of the film, there is a shirtless guy playing the saxophone which is also an homage to the original film.
This film was intended to be a remake of the original set in modern day with Corey Feldman just making a cameo as an homage to the original.
Accompanied by a prequel comic book series titled "Lost Boys: Reign of Frogs".
