It's refreshing to see little Harry in something other than those films, especially something like this. I would've liked to see a little more of Radcliffe's performance rather than him just standing and sitting, but it IS just a teaser. It's great that he's trying to steer away from the little boy wizard, completely moving away from the Family film genre.
The Woman in Black is based on a 1983 novel of the same name, and it lands in theatres February 2012.
