Honky Tonk was a 1941 movie, starring Clark Gable and Lana Turner. Zoe saw it first, told Tom about it in a letter, and Tom later saw it in January of 1942.

From Wikipedia:

This was the first of four pairings of Clark Gable and Lana Turner. Gable and Turner were paired again in Somewhere I’ll Find You (1942). They made two other films together, Homecoming (1948) and Betrayed (1954).

When cast, Lana Turner was only twenty and her star was flying high, having just starred in the successful films Dr. Jekyll and Mr. Hyde and Ziegfeld Girl. MGM was looking to make Turner its replacement for the deceased platinum beauty Jean Harlow and therefore cast her alongside the “King of Hollywood” himself, Clark Gable.

Turner was thrilled at the opportunity of working with Gable, but he was not, as she was twenty years his junior and quite green to the world of Hollywood. When reading lines with her idol, Turner was flustered and blundered quite often. Gable said, “She couldn’t read lines. She didn’t make them mean anything; it was obvious she was an amateur.”

Nevertheless, the pairing proved successful and their steamy scenes together were unnerving to almost everyone, including Mrs. Clark Gable, Carole Lombard. She knew that Gable had an affinity for blondes and upon hearing of Turner’s casting, went to production head Louis B. Mayer and told him to specifically tell Turner that Gable was entirely off-limits.

Lombard had a habit of making surprise visits to the sets and was noticeably present during the bedroom scene with Turner and Gable. Turner was so intimidated by Lombard’s presence that she went into her dressing room and refused to come out. When she did, Lombard was nowhere to be found. While Turner always vehemently denied rumors that she and Gable were involved in an affair, only going as far as to say she was quite smitten with him but looked up to him as more of a father-figure than anything else, it has always been speculated that a Turner and Gable affair had something to do with Lombard’s last minute decision to take a plane back to Los Angeles rather than a train, resulting in the crash which took her life. Turner claimed that the only time she and Gable ever saw each other outside of a professional environment was in the months following Lombard’s death. Louis B. Mayer ordered her to have dinner with Gable at his home that he had shared with Lombard. Turner found him a lonely, broken man and a ghost of his former self.^[3]

Tom’s response, from his letter of February 1, 1942, reads:

I went to the show last night. Steve and Bud and I, we saw “Honky Tonk” some picture now I see what you meant in your letter.
