One of over 100 Columbia features, mostly Westerns, sold to Hygo Television Films in the 1950s, which marketed them under the name of Gail Pictures; opening credits were redesigned, with some titles misspelled, the credit order of the players rearranged, some names misspelled, and new end titles attached, thus eliminating any evidence of their Columbia roots. Apparently, the original material was not retained in most of the cases, and the films have survived, even in the Sony library, only with these haphazardly created replacement opening and end credits.
Although the previous entry states that the replacement title cards eliminated all traces of their Columbia origin, the cast / technical credits for this film are clearly in the style of that studio, and the familiar Columbia fanfare theme can still be heard behind the new title card, which erroneously omits "The" before "Thrill Hunter", and adds a bogus 1933 copyright notice credited to "Gail Pictures International, Corp."; in the eyes of some viewers, these alterations, if overlooked, come over as being both pointless, and not damaging to the general effect of this movie.
Buck claims to be the grandson of the English stage actor Henry Irving (1838-1905)--better known to film audiences at the time. He was the first actor to be knighted in 1895.
One of the main planes shown, depicting Buck flying it, is a 1930 Travel Air D-4000, registration NC477N. This plane can also be seen in Central Airport (1933) and Air Devils (1938). As of 2019 it is still in flying condition at the Owls Head Transportation Museum in Maine.
One of the men running to the crashed plane is wearing coveralls with "Varney Speed Lines" printed on the back - a company founded by Walter Varney (1888-1967), which later became Continental Airlines. Varney previously founded a company that became United Airlines. Both would merge in 2010 into United Airlines.
