"Ray Donovan" is still in production and things are getting better and better for season 4. One of those things involves the inclusion of Richard Brake, of the "Game of Thrones" fame, in the cast.

A report on Deadline says that Blake will play the recurring role of Vlad, described as a powerful and intimidating person who has close ties with some of the most powerful people.

Blake will join the powerhouse cast of "Ray Donovan," adding to the already interesting mix of new characters in season 4.

Along with him are Ted Levine, Lisa Bonet, Dominique Columbus, and Ismael Cruz Cordova. Ted Levine will play the role of a casino owner in Primm, Nevada earning him the nickname, "Little Bill Primm."

Bonet is Marisol described as a woman who holds a powerful secret, while Cordova is a boxing champion named Hector who will connect and share a strong bond with Donovan. On the other hand, Columbus will play the role of Damon, a street-smart teenager who holds a very strong punch. This homeless teen will be involved not only with Donovan, but also with his whole family.

Another addition is Gabriel Mann, who was previously seen on "Revenge." Mann will have a recurring role for three episodes as Jacob Waller, an ambitious and strong attorney to the rich and famous.

Despite these new and interesting characters, Katie Holmes won't be back in season 4 to reprise her role as Paige. As for the other cast members who will reprise their roles, Steven Bauer, who plays Avi, and Dash Mihok, who plays Bunchy Donovan, lead the cast along with Liev Schreiber in the title role as Ray Donovan.

Mihok is excited, saying, "I think there would be a lot of humor and hijinks if Bunchy got to work for Ray. But I'm sure that if the fatherhood thing continues, there's going to be a whole struggle thing with being a parent and the way you view your children when you've been abused—you're totally confused and conflicted."

"Ray Donovan" is rumored to be shown in July 2016 and will consist of 12 episodes.
