It's possible that some more magnetic actors might have helped, but for the first time, Marvel's sharp eye for casting has gone awry. As soon as Robert Downey Jr was seen as Iron Man and Chris Hemsworth as
Thor, it became almost impossible to picture anyone else in the roles. The so-so cast of the Eternals doesn't present that challenge. Madden may look suitably godlike when he poses in a desert and squints at the horizon, but he – like several other key cast members – lacks the acting chops and the charisma to convince you that he is a real person, let alone a real superhuman alien.
