When Bates turns off the recording of Tex using a remote control, what is shown is a Philco "Mystery Control" with the Philco brand name covered up with "Hills". It was the first wireless remote control unit, introduced in 1939 using radio frequency waves to operate Philco radios by tuning preset stations or raising or lowering the volume.
The eighth of sixteen movies with the suave detective nicknamed "The Falcon" and the fifth of ten starring Tom Conway released from 1941 to 1949.
The working title for this entry in The Falcon series was simply "The Falcon in Texas".
Fifth and final film in the Falcon series of Cliff Clark. Seventh and final film in the series of Edward Gargan.
About 23 minutes into the picture, there is a close-up of Detective Bates (Edward Gargan) cutting himself a huge slice of roast beef. Since this film was produced and shown during World War 2, with its attendant rationing - including meat - this sight would have raised quite a reaction from contemporary audiences. And, since at the end of the movie it states, "The picture you have just seen is being shown in combat areas overseas....", even more so from servicemen used to military rations.
