It stars Gregory Peck, Jack Warden and Desi Arnaz, Jr. Filmed on-location in Israel, Billy Two Hats is from a script by Scottish writer Alan Sharp, the screenwriter of Rob Roy and Ulzana's Raid.

Following a bank robbery in the American west, the partner of Scottish outlaw Arch Deans is killed and his young Kiowa half breed friend Billy Two Hats is captured.

As they flee, the sheriff's friend, the trading post owner, named Copeland, takes down his old long-range buffalo rifle and fires a shot that kills Deans' horse, breaking his leg.

Deans persuades Spencer to take him in his wagon to get horses on the condition that Billy stays with Esther to protect her and the homestead from marauding Indians.

"[2] Gene Siskel of the Chicago Tribune gave the film 2 stars out of 4 and wrote, "When the action turns, as inevitably it must, to conversation between Peck and Arnaz, 'Billy Two Hats' becomes vapid.

"[3] Kevin Thomas of the Los Angeles Times wrote, "Writer Alan Sharp's characters are all well-drawn and well-acted, but 'Billy Two Hats'' pacing is too languid and its style too portentous to sustain interest in them.
