The villain Spellbinder is a part of a different Batman's rogue's gallery-- he first appeared fighting the future Batman in Spellbound (1999).
When Bruce and Alfred go to check the surveillance footage, Bruce flips back the head of a bust of Shakespeare to access the security system. In Batman (1966) Bruce also had a Shakespeare bust with a hidden switch to access the Batpoles/Batcave.
The title was spoken by Alfred, just after the opening theme plays.
