WB released IMAX Under The Sea on Blu-ray last week to little fanfare, but it's one of the cleanest transfers out there. It's narrated by Jim Carrey, who sounds like some regular ol' Canadian guy with a calm voice rather than the crazy-go-nuts Carrey he's known for. The Blu includes five featurettes that cover each expedition undertaken to make the 41-minute IMAX feature as well as a behind the scenes piece called Filming IMAX: Under the Sea. Expect to see this in heavy rotation on store display sets. Amazon has the Blu-ray/DVD/Digital Copy combo for a steep $26.99, but it may come down toward the holidays. There's a DVD out there too, but it lacks a) the reason to buy this (the HD transfer), and b) all five "expedition" featurettes.
