Despite being promoted as the true story of Caryl Chessman, on whose book it was based, 'Cell 2455 Death Row' names its lead character 'Whit Whittier' and carries the usual disclaimer during the title credits: "The characters and incidents portrayed and the names used herein are fictitious and any similarity to the name, character or history of any person is entirely accidental and unintentional".
In March 1958, this film was being shown on a double bill with Bitter Victory.
The actors playing Whit Whittier as an adult (William Campbell) and a boy (R. Wright Campbell) are real-life brothers.
The birth name for Caryl Chessman is Carol Whittier Chessman. Whittier is the name used for the convict.
