Blumhouse Productions CEO Jason Blum is so certain the new “Halloween” reboot will be in theaters by next October, he’s willing to bet his hand on it. Blum tells The Wrap, "You can chop my hand off, the prince of horror, you can cut my hand off. That’s on the record." Blumhouse spoke Monday during a tour of the Universal Studios’ Hollywood theme park’s “Horrors of Blumhouse” attraction. It will be part of the park’s Halloween Horror Nights.
