In an early scene you see the sheriff tear the calendar page to show Thursday June 4th. That would be 1874.
The calendar that Randolph Scott tears a page off every day carries an ad for "Gamet's Vegetable Compound." Kenneth Gamet wrote the screenplay for this and several other westerns co-produced by Scott and Harry Joe Brown.
The town in the movie is called Medicine Bend. Randolph Scott appeared later in a movie called "Shoot-Out at Medicine Bend" (1957).
Randolph Scott was 20 years older than his character.
A Lawless Street (1955) was the second collaboration for Randolph Scott and Warner Anderson, as they also appeared in Santa Fe (1951)
