Trying new things can be scary.  As Eduardo Sánchez recently discovered, they can also be absolutely hilarious.  Sánchez is best known for being a co-director of “The Blair Witch Project,” but he’s been directing horror for over 2 decades, including a segment in this year’s horror anthology “Satanic Hispanics.”  Dipping his toe into the horror comedy subgenre,  Sánchez’s “El Vampiro” is a slapstick comedy about a vampire who has to make it home before Daylight Savings.
