Supporting players Barton MacLane and Lyle Talbot would later appear in Perry Mason (1957), starring Raymond Burr.
In the trailer Patricia Ellis is described as "She's the mystery girl in 'The Case of the Lucky Legs,' and all her brains are BELOW the knees. When she steps out, the fun begins."
Third of six "Perry Mason" films from Warner Bros. released from 1934-37.
Mary Treen, who plays Spudsy's wife, had played a telegram office clerk in the series' previous entry, The Case of the Curious Bride (1935).
Though this film version of the Erle Stanley Gardner novel plays out as broad comedy, the story was deadly serious when it was remade in Season 3 of the Perry Mason series with Raymond Burr.
