The first public showing, on 27 April 1944, was at 65 military locations, "from Alaska to Italy, and from England to the jungles of Burma..." (but mostly in Europe).
The film was actually written after its "sequel" The Bells of St. Mary's (1945); in order to borrow Bing Crosby from Paramount for that film, RKO had to allow Leo McCarey to write and direct "Going My Way", based on the same character. Oddly, however, "Going My Way" was released first.
'Barry Fitzgerald' was nominated by the Academy for both Best Actor and Best Supporting Actor awards for the same performance, the only time this has ever happened. He won the Oscar in the supporting category, and lost in the lead category to co-star Bing Crosby.
Filmed in the Santa Monica Church near the beach in Santa Monica, California. Leo McCarey based the 'Barry Fitzgerald' character in part on the church's real (irascible) pastor, Msgnr. Nicholas Conneally.
Added to the National Film Register in 2004.
Earned $16.3 million on its initial run, a huge amount for the time.
The first film to win the Oscars for Best Film and Best Song.
