Sea Monsters 3D: A Prehistoric Adventure review

"There's always a bigger fish," mutters Liam Neeson in The Phantom Menace as he and Ewan McGregor narrowly evade being gobbled up by a Gungan whale. The same logic applies to this latest dinos-in-IMAX offering, one of whose fossilised beasties is discovered to have another's complete skeleton inside its stomach. Choosing one dolphin-like species as its nominal heroes (probably because Dolichorhynchops can be shortened to the anthropomorphic 'Dollies'), this National Geographic production uses eye-catching CG to bring these and a host of other long-snouted, sharp-toothed and multi-tentacled critters to snapping, flapping life. What a pity, then, these sequences are intercut with footage of various beardy archaeologists poring over bones in what must be the least exciting use of 3-D since the Nightmare Before Christmas re-release.
