Krasinski's role, which will be a cameo, is still unknown.
Krasinski is joined by a bevy of big names for the long-anticipated return of the sitcom, which was cancelled by Fox in 2006. Liza Minnelli, Conan O'Brien, Kristen Wiig, and Ben Stiller are some of the previously announced names.
All 15 episodes of Arrested Development will be released simultaneously on Netflix on May 26. The Office series finale is set for Thursday, May 16 at 9/8c on NBC.
