The hardest thing about wrestling a Dan Brown novel into submission for movie purposes would have to be the endless wads of undigested explication that clog the author's narratives. Brown and his reclusive wife/research assistant, Blythe, appear never to have encountered an arcane factoid they could resist cramming into one of his tales. It needn't even be factual. (Their inaccuracies have been widely derided.) The result of this book-crafting strategy has been to give Brown's wooden characters far too many things to explain and to instruct us in. This was already a problem for director Ron Howard in his film version of "The Da Vinci Code" three years ago. Now, taking a whack at "Angels & Demons" — the Brown book that preceded "Da Vinci," but has been extensively revised into a sequel here — Howard has thrown up his hands and gone native. Impatient viewers may want to go home.
Tom Hanks is back, minus the mullet under which he wandered through "Da Vinci," as Harvard symbologist Robert Langdon. And once again he's teamed with a female sidekick — this time a "bio-entanglement physicist" (an actual career path, wonderfully enough) named Vittoria Vetra (Ayelet Zurer). Like Langdon, Vittoria is a stick figure whose sole purpose ( no chemistry, please! ) is to stir the vats of esoteric Brownian blather. She spends most of her time listening to Langdon say things like, "It's the ancient Illuminati threat!" Occasionally, though, she gets to inject some big science into the proceedings herself, causing Langdon to make superfluous comments like, "You're talking about the moment of creation!" There's more to the movie, it must be said; but mainly it's more of that.
