I very much like these new photos, especially the one of Pfeiffer. Her pursed lips and eyes say it all.
As far as Depp as Barnabas, I think he's going to work out wonderfully. The cast photo was a bit underwhelming because he did look so child-like, as others have said, but this newly released photo with the bloodied hands shows the promise of how scary he could be in the character. The thing about Frid's Barnabas that always got me was that he seemed worldly and was intriguing. He drew you with his charm and you did fall in love with him, as someone else said, because of his vulnerability and inherent "good nature" as it were. I never looked at Barnabas as someone I would push through a crowd to jump on top off, but more as someone I would like to spend time with in conversation. As long as Depp captures this aspect of the character, anyone with a bit of romanticism will instantly be attracted.
