VIDEO: 'Constantine' official trailer released

NBC has released the full official trailer for Constantine.

The new series will premiere this fall on Fridays, right after Grimm, at 10 p.m.

The "niche" block of Fridays from 9-11 is actually pretty good!

Constantine is based on the DC Comic Hellblazer featuring the character John Constantine.

The show stars Matt Ryan, Lucy Griffiths, Harold Perrineau and Charles Halford.
