The official Transformers 5 name, along with Optimus Prime and a sword, hit Instagram on Monday. Most plot details for the gallant-sounding film, The Last Knight, are still unknown, but it notably marks Michael Bay’s last run with the saga. “Ready for another ride, Optimus?” the helmer said upon sharing the above teaser and title. “This guy is a machine,” star Mark Wahlberg said. “Huh,” everyone else said. Production begins in June for a summer 2017 release.
