Using most of the character names as was used in the original Tom Tyler film (Monogram) and the remakes starring John Wayne (Lone Star-Monogram) and Bob Baker (Uinversal), it would appear that such an outright theft should have also been noted when the writing credits appear on this film...but try as I may I fail to find one line on any frame of this film that mention this film was base on an original story and screenplay by Wellyn Totman, and also on subsequent screenplays by Robert N. Bradbury and George Waggner. Evidently, the use of previously-written copyrighted material, without crediting any of the original story or screenplay writers is no problem in Canada. A simple based-upon-by nod would have been honest, at least.
