'Quantum of Solace' is latest Bond film

Producers have revealed some of the secrets about the latest James Bond film, due for release later this year, including the inner turmoil that drives its suave super agent hero and its title: 'Quantum of Solace.'

As titles go, it's not as mellifluous as 'From Russia With Love' or 'Goldfinger.' But Daniel Craig, returning as Bond after 2006's 'Casino Royale,' says he likes it.

"It has grown on me," Craig told reporters on the film's set at Pinewood Studios near London on Thursday. "It doesn't trip off the tongue. But why should it?"

Producer Michael G. Wilson said the title, chosen only a few days ago, was taken from a story by Bond creator Ian Fleming that appears in the collection 'For Your Eyes Only.'

Craig said Fleming defined a quantum of solace — it means, roughly, a measure of comfort — as "that spark of niceness in a relationship that if you don't have, you might as well give up."

Filming began earlier this month at Pinewood, the franchise's home since the 1960s. It's a direct sequel to 2006's 'Casino Royale,' beginning an hour after that film ends, with Bond devastated by his betrayal by true love Vesper Lynd.

"He had his heart broken at the end of the last movie and that certainly is a spur for him in this one," Craig said.

"I'd be lying if I said there wasn't revenge in his heart. But it's more than that. That spurs him on, but that's not what the movie is. It's not a revenge movie. It's about him figuring a few things out."

Producer Barbara Broccoli said the film, directed by Marc Forster ('Monster's Ball,' 'The Kite Runner'), mixes Bond's "inner turmoil" with action and of course gadgets as he tries to stop a shadowy cabal trying to bring down the world economy.

Craig's second Bond adventure continues in the gritty vein of 'Casino Royale,' in which a rough-edged 007, newly granted his "license to kill," bled, sweat and felt real emotion. But Wilson promised it also has "twice as much action" as its predecessor.

"It's pretty jam-packed," he said.
