“I’ve accepted the role of Khalar Singh,” he said. “I have no idea how I’m going to do it. First I’m going to find out how I’m going to sound. I’m going to get back on a Mongolian pony and ride like the wind. I’m going to flash my scimitar. I’m going to cut the nuts off Conan and his father.”
A casting breakdown described the character as follows:
Khalar Singh is in his 40s to 50s, Asian or Middle Eastern, Central Asian, Mongol, Turkish, or Persian, open to all ethnicities; commanding in size and manner, a warlord and formidable warrior, brilliant, cruel, weathered and tanned by the many campaigns he has waged and won. He is driven in his quest to find the Queen of Acheron and has been building an empire to do so.
His goal is to find the Queen whose blood will bring life to the demonic minions of Acheron while making himself king of this hellish power. With this power, Khalar will protect his legacy against the onslaught of master sorcerer, Thoth-Amon so that his weak son, Fariq may rule after his death. While riding into a Cimmerian village to recruit his old comrade, Corin, his large collection of mercenaries slaughters them to the last soul when Corin refuses to join them. The villages only survivor was young Conan. When Khalars search has finally narrowed to the likely discovery of the queen at a monastery of female monks, he also learns Conan is older and hungry for revenge
