If Journey 2 is a hit, then who should star in Journey 3?S

Journey to the Center of the Earth starred a ridiculously game Brendan Fraser, who mugged his way through a series of computer-generated situations in 3D. Now the second movie, Journey 2: The Mysterious Island, stars an equally "why the hell not" Dwayne "The Rock" Johnson. Plus an "as long as I get paid" Michael Caine.

Which makes us wonder... given that progression, who should star in the third Journey movie if the second one is a big enough success? We've assembled a list of likely candidates below. Vote for the most fitting successor in the Fraser-Johnson line!
