Continuity mistake: Sabrina wears a pair of big earrings despite not having worn them in the previous shots. (00:10:30)
Continuity mistake: After Sabrina gets off the phone with Faylon, when she leaves her hotel room we see the exterior side of the door and its door knob. Later, when Sabrina returns to her room the doorjamb/casing, wall, and door knob are not the same in the closeup as she fiddles with the lock. Sabrina's ring vanishes in the closeup as well. (00:15:20 - 00:21:15)
Continuity mistake: Sabrina is in New York and she stays at Tuxedo Hotel; her room number is 325. However in a close shot of the key chain, it seems that she stays at another hotel (something like Zarac Hotel), while her room number is 1207. (00:20:30)
Answer: No, Charlie's face was never fully seen. In addition, Charlie was voiced by John Forsythe and he never even came to the set. Whenever we do see Charlie, it's a body double and not Forsythe.
