The Walking Dead boss, Scott Gimple, has confirmed that he wants a crossover to bring the Walking Dead spin-offs together, which could bring the enormously successful post-apocalyptic franchise to a satisfying end. AMC’s original series has grown into an epic franchise comprised of 14 series in the Walking Dead universe. These can get confusing, with The Walking Dead including several time jumps and characters occasionally disappearing, leaving their fates unknown. As a result, there are serveral loose ends for The Walking Dead to wrap up before the franchise ends, so it’s a good sign that Gimple is considering this.
