The sons are so familiar looking
Even as a kid, I always thought I'd seen these actors before, but now that I'm reminded of it, and with IMDb, I can't find anything these kids have been in that I remember seeing. They must just look like your standard 1950s Leave It to Beaver type actors, I guess.
And the little kid reminds me of Corey Feldman-meets-Turtle (from D.A.R.Y.L.), so I easily figured that one out.
