LOS ANGELES — Twenty years after Quentin Tarantino unveiled his first film “Reservoir Dogs,” the director has turned his eye to America's slavery history, spinning a blood-filled retribution tale in his trademark style for “Django Unchained.” Tarantino, 49, has become synonymous with violence and dark humor, after “Inglourious Basterds,” “Kill Bill” and “Pulp Fiction.” In “Django Unchained,” to be released in the US on Dec. 25, he fuses a spaghetti Western cowboy action adventure with a racially charged revenge tale set in the 19th century, before the abolition of slavery in the United States. Jamie Foxx stars as a slave whose freedom is bought by a former dentist, played by Christoph Waltz. The two set off as bounty hunters, rounding up robbers and cattle rustlers before turning their attention to brutal plantation owners in America's Deep South. — Reuters
