"The Parent Trap" in 1961. Loved the Thunderbird the dad drove (even if it wasn't a Mopar), and drove myself crazy trying to figure out the trick photography after my mom told me that Hayley Mills played both the twins.
I've got a great memory. It's just an inch long.
Since we kids went with our parents to the
drive in, we were more interested in the
candy, sodas, and popcorn, than watching
a movie our parents wanted to see.
I do remember my dad moving the car a
few times to find a speaker that worked.
