I don’t know about the movie, but in the TV show, it was Ellie May that went to Harvard Elementary. I think Donna Douglas wasn’t in the movie but was replaced by Erika Eleniak. If the movie followed the original plot, it was Erika Eleniak.
@RedDeerGuy1 I don’t remember him being in the movie & IMDB does not show him as participating either so I don’t think it was. That was NOT one of my fave movies, so I might not remember correctly. Any chance you are thinking of Diedrich Bader who played Jethro???
@LadyMarissa There is a scene where the lawyers from the big oil company are scared that the relative is from Harvard. Turns out it is Harvard elementary school. Grade six, as the smartest family member raises up six fingers.
@RedDeerGuy1 Sorry…I don’t remember that part. Maybe somebody else will remember. It wasn’t a very good movie so I only watched it once & that was 30 years ago. If the light bulb comes on, I’ll be back to enlighten you!!! ;-)
