Diane Keaton is an actress who's also ventured into directing and producing. She is perhaps best known for her various roles in several of Woody Allen's comedies, including 1977's "Annie Hall", for which she won the Academy Award for Best Actress as the title character. She later became a fine dramatic actress in such features as "Looking for Mr. Goodbar" (1977) and "Reds" (1981).
In 1987, Ms. Keaton wrote and directed a documentary, "Heaven", which was about various beliefs concerning the afterlife. It is an excellent movie on the subject, in my opinion.
In 1982, I sent Ms. Keaton two photos, including one of her receiving her Oscar, to her New York City residence. She signed and returned them in just over a week. They can be seen here and here.
Here's the trailer for "Annie Hall".
