Take this with a grain of salt and chase it with a shot of poison but word is John Cena and Dwayne “The Rock” Johnson are up for the role of Superman in Zack Snyder’s upcoming reboot.
I’d say this is pure rumor and in no way true. This happens every time a new superhero movie comes into production. Some wrestling fanatic who is refusing to come to the realization that John Cena can not act to save his life and so he/she starts the rumor. You’ll remember where John Cena was being rumored for Captain America and The Rock was once being toyed with in regards to taking over Superman before Superman Returns. There was also that rumor about Brock Lessner up for Venom in Spiderman 3.
I like Zack Snyder, in my opinion he hasn’t made a bad movie yet and I’m fully behind his take on Superman…that is unless he somehow loses his mind and thinks this is a good idea.
