The great joy of this film is in seeing Vincent Price, Peter Lorre, Basil Rathbone, and Boris Karloff having so much fun. It's America-International Pictures doing something that they were brilliant at, taking some beloved talent and giving them something to amuse their old fans with. Add to the mix comedian Joe E. Brown (in his final screen role) and veteran director Jacques Tourneur, and it's an amazing ball of fun. The entire lot of them were to reteam for another horror comedy called Sweethearts and Horrors, but Peter Lorre's death the next year was the first nail in that coffin.
