Gail Russell was originally hired to play Ann Nelson, but her problems with alcohol, which eventually destroyed her career, resulted in her being replaced by Dorothy Hart before production began.
Note that when Vince comes to see Joe in his office at the laundry company, Joe is flipping a coin. This may, or may not be, a deliberate reference to Raft's character in Scarface (1932) - the source of all coin-flipping gangster characters ever since.
Ann Nelson (Dorothy Hart) drives a 1946 Pontiac Torpedo convertible; on the wrong side of the law, Joe Gargan (George Raft) drives a brand new 1952 Pontiac Chieftain convertible and bad guy Lou Donelli (Paul Stewart) drives a 1952 Chevrolet hard-top convertible.
Joe says he takes home, after taxes, $58 per week. That would equate to about $570 per week in 2020.
The laundry truck is a very rare 1951 Nash Rambler Sedan Delivery.
