One my earliest memories of Patty Duke was watching her in the TV movie "Sweet Charly" which was fairly groundbreaking (1969/70)? For it's day, about an unmarried woman and a Black attorney on the run who bond in an abandoned seaside house.
I didn't realize until much later it had been a BW play starring Bonnie Bedelia and Louis Gosset Jr although I'm not sure if Patty's adaptation was from the play or the original novel.
