Orson Welles at The Magic Castle (1978)

Our host (surreptitiously played by Abb Dickson in disguise) introduces us outside the castle and describes what - and who - are allowed in it, followed by the opening title. Orson enters the building where strange things are happening, and Abb Dickson (in fez) explains about, and demonstrates, the Indian rope trick. He then turns the program over to Abb who introduces a variety of guests.
