We reported two days ago that Warner Bros. gave the go-ahead for this sequel, hiring director Brad Peyton and screenwriters Brian Gunn and Mark Gunn. No details on the story have been revealed yet, but the sequel will be produced by Beau Flynn, Tripp Vinson, and Charlotte Huggins.
Journey 2: The Mysterious Island was a follow-up to 2008's Journey to the Center of the Earth, although Josh Hutcherson was the only actor to return for the second installment, portraying Sean. Dwayne Johnson played Sean's stepfather Hank in Journey 2: The Mysterious Island, and it seems Hank will be imparting more wisdom (and pec-pops) to Sean in Journey 3, even though Josh Hutcherson hasn't officially signed on yet.
Journey 2: The Mysterious Island has grossed over $280 million worldwide since opening in early February. No production schedule was given for Journey 3, although Warner Bros. is eyeing a 2014 release.
