Jim Henson’s Muppets are such iconic, indelible personalities that it’s almost easy to forget they are, in the end, just bits of felt and foam brought to life by a team of talented human performers. But while the puppeteers behind Sesame Street and The Muppets may not be as well known as the characters they’ve created, their stories can be every bit as fascinating.

Last year’s crowd-pleasing doc Being Elmo: A Puppeteer’s Journey told the inspirational true tale of Elmo performer Kevin Clash, and now a group of filmmakers are hoping to give a similar treatment to Big Bird and Oscar the Grouch portrayer Caroll Spinney. Check out a trailer for I Am Big Bird after the jump — and if you like what you see, we’ve got details on how to pitch in for their Kickstarter campaign.

The 78-year-old Spinney has been behind two of Sesame Street‘s most beloved characters since the show began in 1969, working with such visionaries as Frank Oz and Jim Henson. Filmmakers Dave LaMattinaChad Walker, and Clay Frost are working closely with Spinney for I Am Big Bird, which has just gone through pre-production and is now seeking funds for production and post-production.

The feature-length documentary will feature interviews with Spinney and his colleagues, and offer glimpses of Spinney’s home videos, short films, artwork, and personal photos. It seems the plan is to get everything together for a 2013 release. Get a taste of the movie below:
