Indeed.
She had many impressive actors as her leading men: James Stewart, Cary Grant, Clark Gable, James Cagney among others.
But Garner was the one she had the best onscreen chemistry with IMHO.
What I find interesting is supposedly everyone who worked with her thought highly of her, except Alfred Hitchcock. He was not happy with her being cast in his movie “The man who knew too much”. In fact, in the scene where she sings “Que Sera, Sera”, he walked off the set in protest.
I think he liked her as an actress, just not for one of his movies.
I knew James Gardner growing up as Rockford, and his commercials with Mariette Hartley.
I think he was the kind of actor who had great chemistry with women. He seemed like he was the real deal. He did a western with Suzanne Pleshette I liked
