The last movie I saw about an old couple in love was “Right of Way” with Bette Davis & Jimmy Stewart.
They close the garage door & start the engine of his classic Dodge.
Finis.
That was amazingly acted. Two cinema greats at the end of their careers. Right after I saw that movie, I saw On Golden Pond and I thought it was hammy, overdone, and just awful in comparison. Thank you for reminding me about that great movie.
