Satan Never Sleeps is a 1962 American drama romance war film directed by Leo McCarey, his final film, in which he returns to the religious themes of his classics Going My Way (1944) and The Bells of St. Mary's (1945). It also is the final screen appearance of actor Clifton Webb.

Going My Way is a 1944 American musical comedy drama film directed by Leo McCarey and starring Bing Crosby and Barry Fitzgerald. Written by Frank Butler and Frank Cavett, based on a story by McCarey, the film is about a new young priest taking over a parish from an established old veteran. Crosby sings five songs with other songs performed onscreen by Metropolitan Opera's star mezzo-soprano Risë Stevens and the Robert Mitchell Boys Choir. Going My Way was the highest-grossing picture of 1944, and was nominated for ten Academy Awards, winning seven, including Best Picture. Its success helped to make movie exhibitors choose Crosby as the biggest box-office draw of the year, a record he would hold for the remainder of the 1940s. After World War II, Crosby and McCarey presented a copy of the film to Pope Pius XII at the Vatican. Going My Way was followed the next year by a sequel, The Bells of St. Mary's.
