As for the big-name cast, yes it's bigger than Returns had. But they opted for unknowns and character-actors. Something that's economically more feasible for studios (read: cheaper) and done more often. But is that cast going to secure rear-ends on seats during the opening weekend? It didn't for Batman Begins or The Incredible Hulk. It rarely does, to be honest, as great as The Man of Steel's cast is.
It's going to be the character and how they approach him here that's going to sell it. You're right, however, on them utilizing Snyder's action-skills in the presentation. There's going to be a "trailer moment" for sure. Like them firing a tank at Supes and not clipping off his chest like it's a fly or that rumored aerial dogfight footage between the US military and Supes v. Zod & Kryptonian baddies.
Cavill is willing to do interviews and handles them well. He's in a better marketing position that Routh, who didn't have a fanbase as big as Cavill currently has. With the release of Immortals coming, he'll have an even better foothold.
Bale and Edward Norton have similar dark appeal. Incredible Hulk
and Batman Begins
had good actors, but not as popular in a likable way as this cast with Amy Adams, Laurence Fishburne, Keven Foster, and Diane Lane. Amy Adams alone has huge star-power right now, much more than Katie Holmes or Katie Holmes had. Then, add Nolan's popularity.
Star-power does work for marketing generally. Using two movies to say star-power rarely brings in the audience isn't one bit conclusive. Batman Begins
and Incredible Hulk
had other factors working against them. There have been terrible movies that grossed big just because of actor's name. Angelina Jolie, Brad Pitt, Johnny Depp, etc.
