Film has some rather blatant and oddball plugs for Warner Brothers stars. In several scenes photos of Joe E. Brown (whom Lillian Roth sings to) and Dick Powell are seen in the women's cells.
Based on the play "Women in Prison" by Dorothy Mackaye of her own experiences while serving a sentence for concealing and distorting facts regarding the manslaughter trial of Paul Kelly. Kelly, who was having an affair with Mackaye, and Ray Raymond, Mackaye's then-husband, got into a violent, alcohol-induced fight on April 16, 1927. Raymond was seriously beaten about the head, lingered for two days, but succumbed to a brain hemorrhage. Kelly was found guilty of manslaughter and served a little over two years. Mackaye had tried to convince police that Raymond had died of "natural causes". She was released after 10 months.
San Quentin housed both male and female inmates until 1933, when the women's prison at Tehachapi was built.
The car used in the bank holdup is a 1926 Cadillac Series 314. 27,771 were made. Because of this, they are not all that rare, so in excellent condition (an example as seen in this film), at auction in 2017, can fetch around $60,000 - although rare examples with upscale custom coachwork can bring over $100,000. Original MSRP was $3,000 to $5,500 ($60,000 - $110,000 in 2021) depending on the body used.
