There's not much Bryce Dallas Howard in the new Spider-Man 3 trailer - but there is a glimpse.
There's also a glimpse, as fleeting if not more, of James Cromwell as her character Gwen Stacy's Daddy, Captain George Stacy. Knowing what I know about Spider-Man 3 (which, chances are, is a lot more than you - nyah!), I'm not sure he's a completely sympathetic character... not as much as in the books, anyway.
You may have missed his brief appearance in the trailer, so here's a still courtesy of Just Jared. Click on it to make it nice and big.
