When does Get Smart return?

Get Smart is an American comedy television series parodying the secret agent genre that had become widely popular in the first half of the 1960s. It was created by Mel Brooks and Buck Henry, and had its television premiere on NBC on September 18, 1965. The show was followed by the films The Nude Bomb (a 1980 theatrical film made without the involvement of Brooks and Henry) and Get Smart, Again! (a 1989 made-for-TV sequel to the series), as well as a 1995 revival series and a 2008 film remake.
The series centers on bumbling secret agent Maxwell Smart (Adams), aka Agent 86, and his unnamed female partner, Agent 99. The enemies, world-takeover plots, and gadgets seen in Get Smart were a parody of the James Bond film franchise.
