By all means, be excited. But I am not a Wrestling fan and mostly know this Rock fellow from a bad episode of Star Trek: Voyager and that Scorpion King movie. So you can all shout: "THE ROCK!" as much as you like!
From that Planet 51 trailer the astronaut doesn't sound anything like Mr Maivia, but then again it is hard to judge from a trailer when The Rock isn't talking about sticking something up another mans backside. He must be one of teh campest men alive.
For the record, I hate the character of The Rock. i always have and always will. Bloody childish nonsense.
He was great in Get Smart playing a traitor, and hopefully he will do a good job hunting traitors.
Good bye dancing Jazz. May you continue to dance for ever some where else.
