"Lux Radio Theater" broadcast a 60 minute radio adaptation of the movie onOctober 27, 1952 with Dean Jagger reprising his film role.
Parts of the film were rewritten after actor Robert Walker (John Jefferson) died during production. Several scenes use a double shot from behind, and others recycle footage of Walker from Strangers on a Train. The final scene, where a recording of John delivers an anti-communist speech, is lit with a halo around the tape-recorder.
Robert Walker died during the filming of this epic, causing a drastic re-write to the ending and clips from "Stangers on a Train" to be incorporated into it. The scene where he's lying dying in the "car crash" is one such scene.
