At the Justice Magazine office, Jeff has no camera around his next in the establishing shot, but it is there in the next one. When Jessica mockingly proclaims herself to be Spider-Woman to Billy and Jeff, Jeff's camera disappears from around his neck again, and returns when he is shown again.
When Dr. Hagell changes into a human fly, his Gray trousers and black shoes turn into blue trousers and shoes. When he is changed back, the opposite occurs and his lab coat and shirt return as well.
When Billy, Jeff and Dr. Reed think it's safe for Jessica to come out of the closet, Billy is shown in close-up as he says "You've missed all the excitement, Aunt Jessica". It then cuts to a wide shot featuring all the characters, yet the background plate remains the same.
