This movie had to have been released sometime in the 70s and I had to have seen it on TV because I don’t remember it being one of the movies we went to see at the drive-in. I wasn’t old enough to go to the movie theater by myself either.
All that I can remember is that the kid would repeat the words “dig-a-do” over and over when he got nervous or scared. If I remember correct, the kid was maybe 10ish, or younger, and at one point he was in his pajamas saying the words in the dark.
I’ve searched for years trying to find the name of this movie to no avail.
