Question: is there going to be a 3rd 21 jump street

Answer: Yes, On September 10, 2014, a third Jump Street film was confirmed. Channing Tatum has yet to sign on to the project. Tatum stated, ``I don't know if that joke works three times, so we'll see.'' On August 7, 2015, it was revealed that Lord and Miller will not direct the film, but instead write and produce. A first draft of the film's script has been completed. On December 10, 2014, it was revealed that Sony was planning a crossover between Men in Black and Jump Street. The news was leaked after Sony's system was hacked and then confirmed by the directors of the films, Chris Miller and Phil Lord, during an interview about it. James Bobin was announced as the director in January 2016. The title of the crossover was later revealed to be MIB 23, and the crossover would replace a 23 Jump Street film. By August 2016, Jonah Hill considered that MIB 23 would be hard to make, as ``They're trying to make all the deals, but it's kind of impossible with all the Men in Black stuff'', and ``it's hard to maintain that joke when it's so high stakes'' given the film would get too close to the sort of remake, sequel and reboot the previous films mocked. Still, Hill hoped to make a third Jump Street. In December 2016 it was revealed that Rodney Rothman had written a script for the film, and that Bobin is still attached as director for the movie.
