We accidentally missed this earlier on Moviefone, but, as well as the teaser poster, the site also has a little behind-the-scenes featurette on Quantum of Solace, which you can see below.
Some of the B-roll footage has been seen before, but there are some nice glimpses of action sequences and some chat with Daniel Craig. He always seemed very tense in all video interviews for Casino Royale, so it's nice to see him looking a bit more relaxed and like he's enjoying himself.
