I Am Big Bird - a documentary about Caroll Spinney

Being a huge Muppet/Sesame Street fan, I felt the need to look into this. It's a documentary about Caroll Spinney, who has been performing Big Bird and Oscar the Grouch on Sesame Street since the very beginning. He's 78 now, and still going strong, which I think is incredible.
The filmmakers have put together a Kickstarter to help fund the film, and I think it'd be really great to see this movie get made, especially since Kevin Clash (Elmo's performer) just got his own documentary last year.
Here's the trailer.
And here's the link to the Kickstarter page.
What do you guys think? I think it's great to see Spinney get this kind of exposure, and I'm really excited to see the finished film.
