The Fatal Hour

William Nigh, who directed this and the other four films in Monogram Pictures' Mr. Wong series, was a prolific director of B movies, with more than 200 titles in his IMDb filmography. Before turning to directing, Nigh had been an actor, whose credits include being one of the original Keystone Kops in silent comedies for Mack Sennett.

The execution of the murderer's plot requires precise actions during the minutes between 10:00 and 10:15 p.m., to coordinate the radio, the telephone call to the switchboard girl, etc. If one puts together all the information about times and actions given in the four relevant scenes -- in Forbes's home office with Street and Wong, in Tanya's apartment with the switchboard girl explaining to Street what she heard and when, in Wong's discussion with the radio station owner about when the program started and stopped, and in the final confrontation of the murderer with Wong where he explains the timing of his actions -- one sees that the timing described in all these different scenes can't be harmonized. To give only one of many inconsistencies, when Street and Wong enter Forbes's office it is at most 1 or 2 minutes after 10:00 (based on the henchman's announcement of 10:00), and they are there for much less than 13 or 14 minutes of real-time conversation, yet during their time there they get a call from police headquarters about the murder which the switchboard girl didn't report to the police until after 10:15.
