Reagan rarely used a teleprompter unless it was for something extremely long like a State of the Union address. I had opportunity to work with him many times, and he was amazing. We would be shooting a five minute speech/piece for a documentary or something like that, and most of the time, he would nail it perfectly on the first take. It was only after he was out of office and the Alzheimers was taking control that he ever used a teleprompter, and it was quite sad. He hated it.
