In 1956, Franchot Tone starred as the doctor in the 4th Street production of Anton Chekhov's play Uncle Vanya. After the run of the play, Franchot would produce and star in the film version. An interesting bit of trivia is that a young Franchot had originally played a character in a 1929 production of Uncle Vanya in New York in his early theater days.
Dolores Dorn. Because they kept their real-life relationship so private, it is nice to see their interplay in Uncle Vanya scenes. The two were already secretly married when this play was filmed, but film audiences at the time had no idea. Franchot and Dolores had met during the play's first run in New York City in 1956.
I highly recommend Uncle Vanya! It is available on DVD on Amazon.
