While not the equal of past large-format stunners like Everest, the newest adventure travelogue being projected on the Dr. Phillips Cinedome at the Orlando Science Center has its moments of enormity-obsessed transcendence: Any movie can make the sight of an unmanned raft going over a waterfall appear dramatic is worth a gander. The hook here is an expedition to traverse the Nile "from source to sea," learning in the process about the colorful history of the mighty river and the diverse cultures that have sprung up along its banks. Terrifically expansive views of the region's topography and architecture wage a predominantly successful battle against the copious flaws in the Cinedome's screening surface, which looks to be in need of some techie TLC pronto. The largely anonymous crew braves some gunfire from angry locals but otherwise reports that their trip brought them into contact with "happy, good-hearted Muslim people" not the slavering jihadists we're presumed to expect. Patronization alert: Expedition leader Pasquale Scaturro identifies the Ark of the Covenant as "the box that Indiana Jones was after."
