Trivia, insights & behind the scenes
Prison Shadows was produced by the short-lived Puritan Pictures, one of dozens of 'Poverty Row' studios cranking out cheap programmers for double bills.
This barely-feature-length format was designed for the bottom half of double bills—audiences in 1936 would've watched this after a bigger film, which explains the breakneck pacing.
