For the skeptics still holding out for physical proof that the fourth season of Arrested Development was truly, madly, deeply in production: Here's your very first look at the set of the revived show's first episode, courtesy of Michael Bluth himself.

More than just a photo of the first day of filming in progress, the sneak peek offers fans their first real spoiler: It seems Adam DeVine and Anders Holm of the Comedy Central sitcom Workaholics will be making an appearance in the episode.

And where DeMamp and Holmvik are, Blake Anderson can't be far to the right.

AD showrunner Mitch Hurwitz is known to be a fan of Workaholics, and even made an appearance as "Cool Eric" the HR rep in the season 2 episode "Dry Guys."
