Ask family members of someone with Alzheimer's or another dementia: Trying to talk with a loved one who doesn't even remember exactly who they are can be very frustrating.

But here at a senior center in Seattle, things are different.

On one recent day, 15 elderly people were forming a circle. The room is typical — linoleum floors, cellophane flowers on the windows, canes and wheelchairs, and walkers lined up against the wall.

But Carson was intensely private off-screen, and very few people — including members of his own family--really knew him. Documentary filmmaker Peter Jones wanted to try and change that. Once a year, for 15 years, Jones sent Carson a letter, begging him for permission to make a documentary on his life.

"I'd watch these other Capitol Hill staffers and I noticed that they'd just put their hand over the keys in their pockets so they didn't have to waste 30 seconds putting it on the conveyer belt though the security screening — and that didn't set off the alarm when they did that," Sagarin tells host of weekend All Things Considered Guy Raz.

NPR's Michele Kelemen has this behind-the-scenes reporter's notebook of Clinton's most recent swing through Asia.
