A lengthy scene of Meineke trying to find Kindler was filmed but cut by the studio. The footage (between 20-30 minutes) is believed lost as even the original negatives have gone missing. (see alternate versions)
The first film released after WWII that showed footage of the concentration camps.
Though not as well remembered as some of Orson Welles's more original projects, this was the only film directed by Welles to show a profit in its original release.
In one of the final scenes, when Orson Welles lifts Loretta Young one-handed into the clock tower from a ladder, this is not a special effect. Loretta Young stated that this was actually filmed in the church with her dangling dangerously many feet above the church floor.
The vast New England town exterior sets including the church with its 124' clock tower were constructed in Hollywood on the back lot of the United Artists Studio located on Santa Monica Blvd. In some production shots taken by Like Magazine, the circular metal scaffolding of a huge collapsible natural gas storage tank can be seen behind some of the sets. The only such tank nearby a Hollywood studio was a block away from UA.
