And we know her son, Sean Astin, from Lord of the Rings, 50 First Dates, and tons of other movies and TV shows.

He talks to People Magazine about his mom's bipolar disorder, and how he works on her behalf now to raise awareness and help her foundation.

Boise Weekly says the memorial service for Patty Duke is scheduled for Saturday, April 16 at 11 a.m., Pacific time, at Lake City Church in Coeur d'Alene.

The service is open to the public.
