At the TCA press tour yesterday, Robert Rodriguez said that his upcoming “From Dusk Till Dawn” television series will flesh out the stories of Gecko brothers and the Mesoamerican mythology that informed the 1996 film’s vampires. The hourlong drama, which will premiere March 11th on the El Rey network, the cable channel Redriguez launched last month, will follow the film in the beginning, but will later diverge from what happened to take a new path. D.J. Cotrona and Zane Holtz will play Seth and Richie Gecko, the characters played by George Clooney and Quentin Tarantino in the film, and Rodriguez is directing the first two and fourth episodes. Today, El Rey released its first teaser for the series — take a look below.
