The Wet Hot American Summer sequel, Ten Years Later, is a take on an end of the movie segment where the group makes a promise to meet up 10 years later. It'll be an eight episode series set to premiere in 2017 and taking place in 1991. David Wain and Michael Showalter are both returning as writers, with Wain once again helming the director's seat. As for the rest of the cast, we can only guess that most of the original cast will make at least an appearance as they did for First Day of Camp, as well as the possibility of many of the new faces introduced in that series.
