The film was (often unfavorably) compared to John Huston's The Asphalt Jungle (1950), right down to the presence of a pneumatic female starlet in a supporting role. In Huston's film, the wordless part was an early break for Marilyn Monroe. Here, it's a key role for Jayne Mansfield.
In the scene where 'Edward G. Robinson''s character enters the office of DA Ralph Ford (Edward Platt) you can see the Maltese Falcon from John Houston's 1941 film on the barristers bookcase near the entrance door.
(at around 1h 23 mins) During the chase scene, the film is flipped for all three cars as they make a left turn; the steering wheels are on the right side, the license plates are backwards and all the building sign-age is reversed.
Near the end of the film, the Ford automobile that Victor Scott leaves his meeting with Frank Garland in (with Miss Hinkel at the wheel), has hubcaps that are missing, then appear, and then disappear in subsequent shots as the drive proceeds.
When Victor Scott addresses the jury he refers to the 45 revolver used to kill Gloria Benson in the opening scene. The gun in fact is a semi-automatic pistol, not a revolver.
