Caroll Spinney has been playing Big Bird and Oscar the Grouch on "Sesame Street" for 45 years when, after making a humble start as a traveling puppeteer, he was invited by Jim Henson to come to New York to work on "Sesame Street." The rest is history. After decades of stretching and extending his arm to work the giant bird's head (damaging tendons and nerves in the process), Spinney, now 80 years old, has no plan to give up playing Big Bird -- a character who he says is a part of his soul. Years ago, Spinneyhandpicked his ownsuccessor, an understudy who has since waited, quite literally, in the wingsfor almost 20 years.

When his first marriage to a woman embarrassedby hiscareer ended in divorce, Spinney foundDebra, the love of his life, who meticulously documented practically every moment of their marriage and life together. These home videos helped documentary filmmakers Dave LaMattina and Chad Walker piece together a charming film that examines Spinney's story from childhood to small-time puppeteer to portraying one of the most beloved characters in television history.

Years ago,Big Bird's popularity began to wane when stiff competition from other children's programming forced "Sesame Street" to shift its focus to a younger audience. Elmo was introduced, and the writers began to explore different characters. Despite that shift, Big Bird and Oscar remained staples on the show, and it can be said that Big Bird even helped shape the results of the 2012 presidential election. Indiewire spoke with filmmakers Dave LaMattina and Chad Walker as well as Big Bird himself, Caroll Spinney.

What made you guys want to shoot the story of Big Bird and Caroll?

Dave LaMattina: In 2005, I interned at Sesame Workshop. I was in the home video department and I had no idea who Caroll Spinney was. I was telling a friend about the internship and she said "Oh, I'm related to Caroll Spinney," and I said, "Oh that's great! But who is Caroll Spinney?" and she started telling me how Caroll has been Big Bird and Oscar the Grouch since 1969 and he's still doing it and is a really interesting guy. So Chad, myself and our partner Clay [Frost] who is the executive producer, started talking about this as an idea for a documentary and in 2009 we approached Sesame Workshop. They were so supportive from the very beginning and we met Caroll and thankfully he said yes!

Caroll Spinney: I couldn't resist!

You guys used Kickstarter for a portion of this?

DL: We did use Kickstarter. We had talked about Kickstarter almost as early as when we had pitched Caroll. When we approached Caroll with the idea and explained what Kickstarter was and said that the only way we're going to be successful here is if you're supportive of this and participate in the rewards, he was totally on board. So we were able to tap into this amazing audience of people who, like ourselves, grew up on "Sesame Street" and who wanted to see this movie get made. The fact that Caroll participated in the rewards and was involved gave us some unique stuff.

Chad Walker: We were able to hit our goal, which was $100,000, and we actually even surpassed it and made $124,000.

We're really big fans of Kickstarter here at Indiewire.

CS: Yeah, it's a wonderful idea.

The film has a ton of your home videos, Caroll. It must have been a godsend for you guys as documentary filmmakers, that Caroll and Deb had such an extensive library of home videos. Caroll, did it take you a lot of digging to find them? And Dave and Chad, how did you guys go about digging through and finding what you wanted and needed?

CS: Well Deb, my wife, is a really fabulous archivist. She keeps all kinds of things like that. Had it been strictly up to me, I don't think they would have half the movie! She searched and came up with tons of things and they drove away with about three carloads of films.

CW: When we had the meeting with Caroll and Deb, the first meeting where we pitched them on the idea, Deb said, you know I'm not a professional or anything but I've pretty much videotaped everything we've ever done, and at that moment we knew this was going to be an amazing opportunity. Like Caroll said, there were just hundreds and hundreds and hundreds of hours of stuff to go through. In the first box was [footage from] behind the scenes of "Muppet Family Christmas" and "Follow That Bird" and we're losing our minds. Then you had six hours of driving through New Zealand just with the camera sticking out the window that you would go through. But even on those tapes you find little gems, like Caroll running and falling down the hill and Deb laughing at him and stuff like that. It was really remarkable.

There are also a few animated sequences in the film. What inspired those?

CW: That kind of came out of necessity. Caroll would have these amazing stories but there just wasn't any footage of it. So we started thinking about what an interesting way would be to tell the story without anything to cover it and we thought, what's really big in terms of "Sesame Street"? And it was all those little animations and all those little cartoons. That's really where that came from. The whole beginning was this cartoon called "The Noble Ostrich," you can find it on YouTube. that was really the inspiration for the style of the animation, and then also it always seemed like there were numbers and letters flying out of people's mouths to help you learn so that's where the idea for text came from.

They're definitely a nice addition.

CS: It really looks good because it looks like a part of "Sesame Street."
