Released directly to video on Bule-Ray DVD
No credit is hown for a narator. Doubt of this movies success based on it being marketed direct to video is enhance if there is no narration which is the trademark of Shepherd's success.

Note of interest:
Shep always wanted to to a TV series based on his stories and even produced a pilot for ABC based on "Phantom of th open Hearth". Negotiations broke down and in the 80's the "Wonder Years" was created without Shep but using the same format of telling a 'kid' story with narration by the adult kid. For the Wonder Years it was Daniel Stern who provided this voice and it is the same Daniel Stern who plays the part of the "Old Man" in the movie.
