Some very good guesses as to the identifies of these motorists and movies. Here they are:
1. Clifton Webb and Dorothy McGuire in “Three Coins in a Fountain.”
2. Joseph Cotten in “Walk Softly, Stranger” (1950).
3. Rosalind Russell and Arthur Connell in “Picnic” (1955).
4. Maggie McNamara and Louis Jourdan, “Three Coins in a Fountain”.
5. Humphrey Bogart, Gloria Grahame “In a Lonely Place”. This one might have been a bit more difficult because we can't see their faces.
6. William Holden, Cliff Robertson in “Picnic” (1955).
7. Dorothy McGuire, Van Johnson in “Invitation” (1951).
