Castlevania has been automatically greenlit for at least two seasons (or a first season to be released in two separate chunks). The Belmont family will definitely be making their streaming debut later this year although likely not in October, when*Stranger Things*season 2*arrives and aiming to*dominate*in all of their vampire-slaying glory.
As noted by*io9, the*Castlevania*TV series is most likely*being developed by*Adventure Times Frederator Network (who teased his involvement near the end of 2016) and*produced by Adi Shankar known for his*Power Rangers fan film that garnered a lot of attention in 2015.
