A new teaser, entitled 'Heavy Bag,' for Season 4 of Ray Donovan has been unveiled.

In the clip Ray (Liev Schreiber) is seen battling his demons as he takes it all out on a big punching bag. Voices from various people in his life and interactions echo back, stuff that haunts him. Ray looks exhausted and frail as he punches the bag, dealing with the many accusations and confessions that drag him down.

This is the second teaser for upcoming season that has been unveiled. The first official teaser was unveiled earlier this month. That clip only emphasizes how despite Ray's acknowledgment of his waywardness and bid for salvation he will continue to ride the dangerous spiral he has thus far. This time around it seems like he is really going to alienate his family. Ray's daughter Bridget is seen living away from the family and deeply disappointed in her father and questioning his love for the family. Ray is seen requesting her to come home, promising her that he has changed and is different. In another sequence Abby (Paula Malcolmson) is seen getting an MRI, suggestive of some major illness. In fact even Mickey (Jon Voight) is seen in hospital. The teaser is aptly titled 'I have sinned.' Through the teaser Ray is seen committing to the same messy affairs as before, nothing seems to have changed.

The teaser does not reveal some of the new cast members and guest stars that have joined for this season.

The latest cast announcement was the addition of Game of Thrones actor Richard Brake.

According to a Deadline report, Brake is set to play a recurring role in the Showtime series. He will be playing the part of Vlad, "a dangerous and intimidating man who works for some very powerful people."

Previously, it was revealed that actor Dominique Columbus will be joining the cast. Deadline revealed that Columbus will be playing the part of "Damon, described as a street-smart, homeless teen who packs a mean punch and becomes involved with the Donovan family."

This development came at the heels of another casting announcement for the show, TVLine revealed that Lisa Bonet -- best known for her work on The Cosby Show -- will play the part of Marisol, "an unstable woman with a damaging secret."

These two join a bunch of other new cast members for the show of late.

Previously, Deadline reported that Ted Levine and Ismael Cruz Cordova are set to come on board season 4 of Ray Donovan.
