Relying on the combined creative imagination of writers Jonathan Swift, Robert Louis Stevenson and Jules Verne, it has returning young star Josh Hutcherson as Sean Anderson. He receives a coded message from his grandfather (Michael Caine) who went to search for the elusive Mysterious Island, and never returned.
His stepfather, Hank (Johnson) helps him decode the message and the two of them head off to Papua, to find dear ole granddad.
When they arrive, Hank hires a helicopter pilot as a guide, played by Luis Guzman, who's along for laughs and his daughter played by Vanessa Hydgens, who's along for a love interest for Hutcherson. After passing through some very rough weather, they find the Island, which provides danger, beauty and most importantly, adventure.
Grandpa leads them on a wild ride to escape huge attacking birds by holding on for dear life to the backs of large bees, outrunning an irate lizard and on a search for a way to get off the Island and go home ( Kristin Davis is underused as mom waiting for them to return).
Special effects are spotty - the wildlife was mostly ferocious and fun, but the vegetation was very hokey-looking.
Michael Caine always brings an interesting take to each of his characters, here he has just about the right amount of cantankerous spunk and Johnson's easy-going manner and big smile gives him a very pleasant on-screen presence.
