When Biff asks for a package of Sen-Sen at the pool hall, audiences at the time would have known he was buying a popular brand of breath freshener. It was produced from the late 1800s until 2013.
After Fredric March read the play, he told Gary Cooper about it, and Cooper urged Paramount to buy the film rights to it, which they did for $26,000 (about $620,000 in 2023).
There have been six television productions of the play: One Sunday Afternoon (1949), One Sunday Afternoon (1951), One Sunday Afternoon (1952), One Sunday Afternoon (1954), One Sunday Afternoon (1957), and The Strawberry Blonde (1959).
This film was one of three Paramount sound features acquired by Warner Bros., along with The Letter (1929) and A Farewell to Arms (1932) with the intention of remaking (though the latter was never remade by WB). These films would join the "Popeye" cartoons as properties originally by Paramount that were sold in 1956 to a.a.p. (Associated Artists Productions, later United Artists Television).
