Sony has released a new trailer for The Dark Tower, the sci-fi western based on the Stephen King novels (Marvel did comics based on the novels).  Promotion has seemed light for this film, which was finally made after a long period in development hell.  It was originally scheduled for January release and was delayed until August 4.

The first trailer was released in May (see "First 'The Dark Tower' Trailer") to good response (over 15 million views).
