Many thanks to Sally Parker Menchaca who has shared a photo on FB and to @LavenderFlo for tweeting the link.
It is a group photo of Keanu and Melody Chase who played Bob Arctor’s wife and Sarah Jane Menchaca who played one of Arctor’s daughters in the the film.
@LavenderFlo also shared another photo of the group that has since been removed from Melody Chase’s IMDb page.
