Despite this, Sutherland was who the bosses truly desired to be cast as Red, due to success in the movies ‘24’ and ‘Designated Survivor.’

However, due to scheduling conflicts, the A-lister wasn’t able to take on the role as he often tours with his band The Kiefer Sutherland Band, whenever he’s away from the screens.

Nevertheless, Spader impressed both Eisendrath and Bokenkamp as they disclosed: “I don’t think any of us knew just how good he was going to be.

“He’s amazing in it, and it was really fun to watch him just become this person. That was a joy to see.”

The Blacklist is available on NBC. A UK release date has yet to be announced.
