21 Jump Street star Channing Tatum has hyped up the script for the ill-fated crossover sequel, 23 Jump Street, aka MiB 23, calling the script the best he has ever read for a third movie in a trilogy. Discussing the doomed project with Comicbook.com, Tatum will no doubt have action-comedy fans feeling even more saddened that we will likely never see the Jump Street/Men in Black crossover movie on the big screen.
