There are a several moments of real pathos in Ron Howard’s film of Dan Brown’s “Angels & Demons,” which is several more than he was able to conjure up in his film of Brown’s “The Da Vinci Code.” Howard has made a better, more entertaining thriller out of the first book in Brown’s saga about symbols expert Robert Langdon (Tom Hanks) and his research into skullduggery entangling the Catholic Church.

The director loses “the girl” for much of the film, and loses his hero for much of the third act. The script tips its hand too early, and can’t quite turn Langdon into Indiana Langdon on his Last Crusade. But in plumbing the mysteries of the Vatican (which refused to help with the film), the Conclave of Cardinals who elect a new pope, the machinery of the Vatican State and the treasures of the Vatican Archive, Howard has made a popcorny summer movie that mimics the history-meets-action of those escapist “National Treasure” movies.

This time, the threat is directly to the Vatican. Someone has kidnapped four cardinals who are the leading candidates to succeed the just-deceased pope. Someone has just stolen the dangerous byproduct of science’s new cutting edge – anti-matter created by the new supercollider in Cern, Switzerland. Could that “someone” be The Illuminati, that long-dead secret society of enlightened scientists? Are they back and ready for revenge, eager to murder cardinals and blow up the Vatican?

The late pope’s right-hand priest (Ewan McGregor) thinks so, though the chief of the Swiss Guards (Stellan Skarsgard), charged with protecting the Holy See, is skeptical. They have mere hours to solve a puzzle and prevent the destruction of St. Peter’s and the Vatican.

Howard builds suspense by intercutting the race to rescue the cardinals with the political machinations of the men selecting a new pope, chief among them Cardinal Strauss (Armin Mueller-Stahl). Hanks is more engaged this time, and McGregor, Skarsgard and Mueller-Stahl give formidable support.

This could have easily just been “The Galileo Code” but the screenwriters (Akiva Goldsman and David Koepp) and Howard wrestle a little science fiction and science morality into “Angels.”

It’s doesn’t quite pay off, but “Angels & Demons” does a much better job of balancing the blasphemy and blood, heresy and heroics that were Brown’s ticket to eternal wealth if not eternal life.
