(CBS News) George H.W. Bush, the 41st President of the United States, is the subject of a revealing new HBO documentary called "41."
Writer-director-producer Jeffrey Roth said the Bush family "seemed to enjoy it" at a screening Tuesday night at near the family's summer home in Kennebunkport, Maine.
Roth said he intended the film to capture the former president as a person, "a man who did fascinating things in his life."
The elder Bush doesn't like to talk about himself, so Roth said he was surprised to hear in an e-mail - after initial refusals from his representatives - that he was "intrigued" by the idea of a film about him.
"We had this unique opportunity to be with him to tell the story in his own words, which historically has not been done before," Roth said. "And yet to try to get him to talk about himself for somebody who doesn't like to talk about himself was very difficult to do."
