#3 The Rock

Few wrestling fans would have predicted the success The Rock would go on to have when he left the WWE for Hollywood in 2004.
Dwayne 'The Rock' Johnson is probably the biggest movie star on the planet right now, and whatever the costs, the WWE should make sure he is in the middle of the ring on April 8th, 2019.
The Rock is still in ridiculous shape, and there is no doubt that he would still be able to pull of a top quality match on the night.
The list of potential opponents for The Rock at Mania is as big as the man's biceps, but a match with Brock Lesnar is arguably the biggest.
The two men are two of the biggest box office draws on the planet, and having them square off could even break the box-office record set by Cena and The Rock at WrestleMania 28.
