Phillip Borsos first learned about
Bill Miner as a teenager and wanted to adapt Miner's life into film;
The Grey Fox was the first feature-length narrative film directed by Borsos.
Harry Dean Stanton was originally planned to star as Miner and ads were taken out featuring him as Miner. However, he withdrew from the production in order to star in
One from the Heart and
Richard Farnsworth was selected to replace him. According to Farnsworth, the "picture company" was the only one ever allowed to film at
Fort Steele, British Columbia, a
heritage site.
The Grey Fox was also filmed on the
British Columbia Railway /
Pacific Great Eastern Railway, now run by
Canadian National Railway, between
Pemberton and
Lillooet, British Columbia, and the Lake Whatcom Railway between Wickersham and Park, Washington. The capture sequence was shot a quarter of a mile from where Miner was actually caught. Miner's gun, "a .41 Bisley Colt", was obtained from a collector and used by Farnsworth in close-ups. Scenes from
The Great Train Robbery are intercut with new footage made to look similar to the older footage. The film was funded by selling 696 units for $5,000 each to investors, and it was edited in 1981 before a distributor was found.
Phillip Borsos was paid $45,000 to direct the film. The film was shot from 7 October to 28 November 1980, and had a budget of $3,480,000 (), but cost $4,500,000 () to make. ==Release==
