The Speck Brothers are two brothers who are Slavers encountered in the opening scene of Django Unchained. Composed of Ace and Dicky Speck, the Speck brothers are two seasoned slavers and overseers who have purchased Django and the other slaves at the Greenville auction in the slave market at Greenville, Mississippi.
Django was sold to the Speck brothers by Old man Carruccan, Django's former owner, for an attempted escape with his wife Broomhilda Von Schaft, from the Carruccan Plantation.
In the opening scene, it appears that the Speck brothers have driven Django and the other slaves into Texas, possibly looking for opportunities to sell on the Western frontiers. No mention is made for their destination, so it is assumed the Speck brothers have not purchased the slaves on behalf of another plantation.
When approached by Dr. King Schultz in the dead of night, the Speck brothers are weary of the lone traveller. Schultz then enquires amongst the Slaves and in particular Django over the identity and location of the Brittle brothers, whom Dr. Schultz is tracking as bounty. The Speck brothers, upon revelation that Dr. Schultz is a bounty hunter, attempt to ward him off, threatening him at gunpoint. In response, Schultz kills Ace Speck and shoots Dicky Speck's horse Roscoe.
With Ace Speck dead and Dicky Speck incapacitated with a broken leg under his dead horse, Django commandeers Ace's horse and relieves him of his coat, much to the anger of Dicky. Schultz pays the remaining Speck brother a total of 125 US Dollars for Django and Ace's horse. As the pair leave, Dr. Schultz gives the remaining slaves two options. One, carry the injured Dicky Speck 37 miles back the way they came. Or two, take Ace Speck's shotgun and kill Dicky Speck, then head north with the money.
As Dr. Schultz and Django leave, Dicky Speck is last seen pleading for mercy as the slaves approach and surround him slowly, finally killing him with Ace's shotgun. The fate of the Speck brothers are never mentioned again, and it is assumed that the slaves simply buried the corpses of the Speck brothers in the vast, rural wilderness of the Deep South.
