My favorite James Garner movie was "Murphey's Romance" which he did with Sally Field. He played a much older suitor to a young woman whose sorry but handsome young husband had left her. I remember the movie for the last lines mostly. He said something about how he wasn't young anymore and he had a lot of miles on him, but he was steady, and then he said and "I'm in love for the last time in my life."
I've always remembered that line. If you've never seen the movie check it out sometimes.
It's a great love story without being "mushy" at all.
