Due to the success of El renacido (The Revenant) (2015), which sparked a growing interest in this film, Warner Brothers released this movie on Blu-ray on August 16, 2016, as part of their Warner Archive Collection.
Zachary Bass, who is based on real-life mountain man Hugh Glass, is shown to have had a wife and son in this movie. However, there's no record of the noted historical figure ever being married and having any children. Similarly, in El renacido (The Revenant) (2015) Glass was also shown to have a wife and son.
Zachary (Richard Harris) is based on real-life mountain man Hugh Glass. One of the two men left behind to await Glass' death was a very young Jim Bridger.
The reason why some of the names and events were altered in this film was because the filmmakers wanted to avoid paying rights fees to Frederick Manfred, whose 1954 novel "Lord Grizzly" was based on Hugh Glass' ordeal and journey. Manfred has stated that the film was not what he envisioned. He was so appalled by the lack of credit that he threatened to sue the producers. They ended up settling out of court.
