Allee Willis was an American eccentric best-known as a songwriter, writing or co-writing “I’ll Be There For You” (1994, Friends theme song); “September” (1978) and “Boogie Wonderland” (1979) by Earth, Wind & Fire; and “What Have I Done to Deserve This?” (1987) by Pet Shop Boys.
There are plenty of short portraits of her on YouTube, most of them filmed in her house which, she says, was the MGM partyhouse built in 1937.
There is also her 1974 album Child Star.
She also recorded the song “Big Adventure” (1985) with Pee-Wee Herman.
Albert Maysles was an American documentary filmmaker best-known for the documentaries Gimme Shelter (1970) Grey Gardens (1975).
He is best known for the direct cinema/cinéma vérité – documentaries he made with his brother.
You can watch Gimme Shelter and Grey Gardens in their totalities on YouTube. And Salesman too (practically).
If your new to the Maysles, I’d start with Grey Gardens, the story of an eccentric mother and daugther.
