Timeless Season 1 Cast Misha Collins

Timeless Enlists Supernatural Star Misha Collins as Eliot Ness

Timeless is staging a second Supernatural reunion.

Just weeks after news of Jim Beaver’s recurring role, Misha Collins — who plays Castiel on the aforementioned CW series — is set to reunite with his former boss Eric Kripke on the time-hopping NBC drama, it was announced Monday.

Collins will play Untouchables leader Eliot Ness in the episode “Public Enemy No. 1.,” which finds Flynn traveling to 1931 Chicago to partner with gangster Al Capone (Tyrant‘s Cameron Gharaee). Lucy, Wyatt and Rufus, meanwhile, team up with the only man who can bring Capone down: federal law-enforcement agent Ness.

“When the Eliot Ness character first came up, I immediately thought of Misha, and I’m so thrilled to be working with him again,” Kripke said in a statement. “Misha brings his charisma, his talent, and frankly, all of his angelic qualities to the role.”

Collins tweeted about the news after it broke:

Interestingly, Supernatural also featured Ness as a character (played by The X-Files‘ Nicholas Lea) in a Season 7 installment.

Timeless returns tonight at 10/9c on NBC; Collins’ episode airs Feb. 13.
