Abbott and Costello are Detectives straight out of Detective school in this story where they end up working for a boxer that has escaped from prisoner after being wrongfully accused. With the help of a formula he turns into The Invisible Man. Costello does his typical stumbling and bumbling and gasping for air and they eventually end up proving his innocence after Costello poses as a boxer in order to flush out the bad guys that framed the Invisible Man. There are some good special effects for the Invisible Man portion of the film. The one thing it was missing was a really good signature Abbott and Costello bit. The best bit they had in the film was an old money gag that was straight out of the Marx Brothers.
Otherwise it was a good film.
