I still understand why Warner Brothers did what it did, but there's no doubt the trailers and the majority of the TV spots affected the film's grosses for its first weeks. That marketing campaign didn't do the film or the studio any favors.
And what's truly unfortunate is that a film's first couple of weeks tend to be when it brings in the lion's share of its gross.
69 days 11 hours 57 minutes 40 seconds since the Depp/Burton Dark Shadows has been in release(ET)!!
