It’s been nearly six years since “Hannibal” ended its run on NBC. The series was seemingly expected to be picked up for a fourth season but the network surprisingly canceled the acclaimed thriller, leaving fans to wonder what might have happened next. Then the show arrived on Netflix and found an entirely new audience, making “Hannibal” more popular now than ever before, leading to even more questions about a possible fourth season. Well, adding some fuel to that fire is the series’ star Mads Mikkelsen, who played Hannibal Lecter in those first three seasons, who thinks the growing fanbase is creating more conversation about a possible return to the serial killer world.
