It has been known since about January that Bautista would be in the Dune reboot, it was always speculated as to what part he would actually be playing. That speculation has ended now that the man himself confirms he will be playing Rabban Harkonnen. In the Dune universe, the character is known for being pretty sadistic and cruel but not very cunning or smart really. and even killed his own father at one point. How this will be portrayed in the movie will be interesting, but it is definitely a part Dave is capable of playing. Best wishes and may the gaming gods bring you glory.
