The Bigger Star:Andre the Giant or Undertaker?
Undertaker is not a household name. Sorry. Maybe in your household, where there are wrestling fans, but nobody outside of wrestling knows who he is. A brief appearance in Suburban Commando does not lead to worldwide stardom. Nobody used Undertaker's face in viral graffiti campaign, he doesn't regularly get referenced in modern media, and he was never the subject of documentaries not produced by the WWE. All of those things can be said of Andre.Undertaker is probably the biggest name in wrestling who just mainly stuck to wrestling.
i would say Undertaker is pretty much a household name himself, which deserves a lot of praise for how popular he is, considering he never did much in the way of TV/movies or anything.
But Andre was big. Andre might even be the 4th biggest, after the Big Three. Undertaker is definitely somewhere in there, in that top ten easily, but he just was never as big as some of those guys, and some of those guys had a lot more marketing outside of wrestling to help that.
