A zany spoof of The Phantom of the Opera, this standard comedy succeeds mainly because of the talents of Tin-Tan who shares Mexico's highest-ranking comic stature with Cantinflas. The story is aided and abetted by the usual song and dance numbers, as all the characters of the original "Phantom" (and more) parade by --- ghosts, tough guys, monsters, and others, including the requisite charming female or two. Although the story could be improved in the scripting department, it still offers a good, enjoyable hour and a half to the younger set of viewers. ~ Eleanor Mannikka, All Movie Guide
