Supernatural Video: Castiel’s in Trouble — Plus: Scoop on the Das Boot Hour

When Supernatural returns this Wednesday (The CW, 9/8c), Dean and Castiel will be looking for a way to rescue Sam from Hell — but soon, the Winchesters will need to save their angelic buddy, too.

A fresh trailer for Season 11 showcases Cas getting close to Amara and Rowena, albeit in totally different ways, while Sam and Dean talk about “getting him back.”

“No matter how much it hurts, no matter how hard it gets, we gotta keep grinding,” Dean says. “And that’s how we’re going to win. We’re going to save Cas. We’re going to ice the Devil. And we’re going to shank The Darkness and anyone that gets in our way — or God help them.”

Also seen in the video: a first look at the show’s foray into the world of professional wrestling, guest starring The Miz, and an homage to an epic German film.

“We’re going to have an episode that is essentially our version of Das Boot, in which much of the episode will take place in a World War II submarine,” executive producer Jeremy Carver tells TVLine, adding that the hour “looks awesome, to pat the entire production on their back. These guys did an amazing job.”
