Thank you to Laura from Laura's Miscellaneous Musings for suggesting this couple to me! Catherine Craig played the bride Julia in You Were Never Lovelier (1942) which was one of the titles in my Weddings in Film series.
James Garner and Lois Fleishman Clarke met in 1956 at a political rally. They married two weeks after meeting and have been married ever since. In Garner's memoir, The Garner Files, he says
"It was love at first sight. The 'thunderbolt.' She was as beautiful as she was sweet... I was nuts about her from the moment we met. Still am."
