As far as other current WWE talent is concerned, guys like Mike “The Miz” Miznan and Randy Orton have recent television appearances, and there’s plenty of other entertaining stars (The New Day) that wrestling fans would fall over themselves to watch in another capacity.
Speaking of WWE legends, Bill Goldberg is confirmed to be appearing on The Flash soon, so add him to the list.
As far as who the WWE could bring to some of its future programming, current WWE part-timer John Cena seems to be a reasonable guess, considering he tried reality television in the past, and everyone loves him.
There’s also WWE legend Adam “Edge” Copeland, who has a sizable acting pedigree, and with his inability to perform in the ring anymore, he’s also a guy with a lot of non-wrestling time on his hands.
