Dwayne Johnson seems to be another actor intent upon busying himself with every available project. We reported here on some stills from his upcoming revenge thriller “Faster”, along with news of his involvement in the next “Fast & Furious” film and the upcoming action-comedy “The Other Guys”.

Now, Heat Vision report that Johnson is to appear in the sequel to the Brendan Fraser-starring “Journey to the Center of the Earth”, currently bearing the title, “Journey 2: The Mysterious Island”. The first “Journey” was an adaptation of Jules Verne’s novel and got the jump on the recent vogue for 3-D features. The sequel will be similarly shot and screened in 3-D and loosely based on Verne’s “The Mysterious Island”.

Josh Hutcherson will return to the role of Sean Anderson from the first film and with Brendan Fraser unable to participate in the sequel to the $250m-making original due to a scheduling conflict, his Rock-ness will play the new role of the boyfriend of Hutcherson’s mother, with the group of them heading off for the titular island in search of Hutcherson’s missing grandfather. Heat Vision say that Johnson is still in negotiations for the role, however a deal is expected to be concluded this week, with New Line looking for a late October start for filming in Hawaii and North Carolina.

Despite Johnson’s other current projects having a less kid-friendly vibe, he seems to want to keep his hand in the family adventure genre after Race to Witch Mountain. Further casting news is expected over the next couple of weeks and we’ll update you as we hear it.
