Riddick is a 2013 science fiction action film written and directed by David Twohy, based on the character Richard B. Riddick by Jim and Ken Wheat. It is the third installment in The Chronicles of Riddick film series and a sequel to both Pitch Black (2000) and The Chronicles of Riddick (2004). Vin Diesel reprises his role as the eponymous character alongside Jordi Mollà, Matt Nable, Katee Sackhoff, Dave Bautista, Bokeem Woodbine, Raoul Trujillo, and Karl Urban. In the film, notorious murderer Riddick is betrayed and left for dead on a desolate planet and uses his instincts to survive. He eventually teams up with mercenaries arriving to capture him to escape from a larger threat. Riddick was released in the United States on September 6, 2013. Critics considered it a return to form for the series and it became a moderate box-office success compared to its predecessor. A fourth film, entitled Riddick: Furya, is in development.

Five years after Kyra’s death, Riddick has become uneasy in his role as Lord Marshal of the Necromonger fleet. His refusal to swear into the Necromonger faith has caused dissent among his subjects. After the latest attempt on his life, Riddick strikes a deal with Commander Vaako: the location of Furya and a ship to take him there, in exchange for Vaako succeeding him as the next Lord Marshal so that he can achieve transcendence. Led by Vaako’s aide, Krone, Riddick and a group of Necromongers arrive on a desolate planet. Realizing that it is not Furya, Riddick kills most of his escorts when they attempt to assassinate him; Krone causes a landslide and buries Riddick alive.

Riddick emerges from the rubble with a broken leg, which he sets and splints while fending off native predators: vulture-like flying animals, packs of jackal-like beasts, and giant venomous scorpion-like water-dwelling Mud Demons. Needing time to heal, Riddick hides himself within some abandoned ruins. After he’s fully healed, Riddick notices a vast savanna beyond some rocky cliffs, but the only passage through is impeded by several muddy pools infested with Mud Demons.

He begins injecting himself with Mud Demon venom to build an immunity and constructs improvised melee weapons, as well as raising and training an orphaned jackal-beast pup. He kills the Mud Demons blocking his entrance and reaches the savanna. After finding a mercenary station, Riddick notices a series of approaching storms and concludes they will unleash a dangerous threat. Riddick activates an emergency beacon at the station, which broadcasts his identity to mercenary groups within the area.
