The next chapter of the Marvel Cinematic Universe was supposed to be ushered in with Thunderbolts, featuring a massive team-up of the MCU’s best anti-heroes, like John Walker and Yelena Belova. The movie was also supposed to introduce The Walking Dead and Beef star Steven Yeun as Sentry, a tragic villain with the “power of a thousand suns” who could become a central figure of the MCU Phase 6.
