Manhattan (sometimes styled MANH(A)TTAN) is an American drama television series based on the project of the same name that produced the first atomic weapons. While some historical figures appear in Manhattan, most characters are fictional, and the show is not intended to maintain historical accuracy.The show was the first drama production for WGN America since the revival of Tribune's production arm as Tribune Studios. The series premiered on WGN America on July 27, 2014. The series earned critical acclaim throughout its run, but failed to secure adequate ratings. As a result, it was canceled on February 2, 2016, after its second season, becoming the first WGN America original series to be canceled.
