While Saturday was a big day for film promos, a couple of TV series also dropped a few key trailers as well. Dirk Gently's Holistic Detective Agency Chief amongst them was "Dirk Gently's Holistic Detective Agency," the new Max Landis produced TV series take on the classic Douglas Adams book. Elijah Wood and Samuel Barnett topline the eight-episode series which follows the time-and-space-shifting adventures of eccentric 'holistic' detective Dirk Gently (Barnett) and his reluctant assistant Todd (Wood).
