WATCH the Trailer for the 'Arrested Development' Documentary

Before Arrested Development Returns on Netflix in 2012, a Doc on the Series Will Be Released in December

After years of rumors, false starts and rumors of false starts, we know for real, for certain, that new episodes of beloved, but canceled Fox comedy Arrested Development will debut next year, on Netflix.

But before the show returns, a long-in development documentary on the series will debut, in December, and the final trailer for the fan-made doc reveals that it will include interview with the cast, crew, creators and guest stars of AD, as well as lots of fans who'll recall how they got hooked on the unique comedy with its first episode.

Among those whose interviews are previewed in the trailer: series creator Mitch Hurwitz, who jokes that there are more AD fans in the documentary than there are AD fans out in the rest of the world, as well as executive producers Ron Howard and Brian Grazer.

Cast members Will Arnett, Tony Hale, Portia de Rossi, Jeffrey Tambor and David Cross also sit down with the filmmakers, as do guest stars Scott Baio (who recalls learning the name of his character -- Bob Loblaw) and Henry Winkler, who plays Bluth family attorney Barry Zuckercorn, a character Howard says is Winkler's all-time favorite role (after The Fonz, of course).

The still-untitled documentary, which is scheduled to be released on December 22, was made by a pair of Arrested Development superfans, Jeff Smith and Neil Lieberman, who funded the project themselves and travelled all across the country to interview their fellow AD devoted for the film.
