Goofs

In one scene, Britt Reid is laid up in his study with a gunshot wound to the shoulder suffered as the Green Hornet, and he, Kato, and Scanlon are trying to figure out a way for him to get medical treatment without exposing his secret identity. Van Williams read a line one way in the master shot, and another way in his close-up. The editor nevertheless cut from the former to the latter in mid-sentence, resulting in this: "I never knew how much trouble one little bullet could cause so much trouble."

When the Green Hornet is telling the crooked cops that one of their buttons was found at the crime scene, the view from the front shows the Hornet's gloved hand pointing at the cops. The next view from behind shows a bare hand pointing at the cops.

The producers used the same automobile footage twice: a blue Mustang convertible is pulling into the hospital parking lot in two different scenes on two different days. The cars to the right of the Mustang are also identical in both scenes.
