Tarantino's fundamental inspiration stems from the original 1966 shoot-'em-up "Django," a precedent rendered in obvious terms from the opening credits, when the bouncy theme song from Sergio Corbucci's classic spaghetti western makes its first appearance.
As with most Tarantino movies, this one’s brimming with the director’s signature pop-cultural mixology, including a soundtrack with tracks by rapper 2Pac and James Brown, Jim Croce and John Denver, and the theme song to the original 1966 movie, “Django,” from which this one takes its inspiration as well as its title.
The title is an homage to "Django," Sergio Corbucci's over-the-top Spaghetti Western from 1966 starring Franco Nero.
Like "Inglourious Basterds," Tarantino's latest borrows its name and attitude from an old Italian flick, in this case the 1966 Spaghetti Western "Django."
You know from Tarantino’s audacious choice of intro music — the haunting theme song from Sergio Corbucci’s iconic 1966 Spaghetti Western “Django,” that the maestro-of-all-things-tasty has many surprises in store for his delighted audience.
In the same way that Kill Bill paid tribute through imitation to Japanese samurai and Chinese kung fu films, Django Unchained serves as Tarantino’s blood splattered love letter to the work of Leone (A Fistful of Dollars), Corbucci (Django, The Great Silence), Sollima (The Big Gundown) and probably dozens of other filmmakers who most of us have never even heard of, but whose movies’ Tarantino can no doubt recite verbatim.
