4. Lara Lee Candie-Fitzwilly
There aren't a ton of women in "Django Unchained," the most prominent being Kerry Washington as Broomhilda, who features heavily throughout the trailer. But there's one other: Lara Lee Candie-Fitzwilly, the widowed sister of Calvin Candie (Leonardo DiCaprio), who's just as unpleasant a person as her brother. We'd pegged possibilities like Christina Hendricks and Uma Thurman for the role, but in fact it was a a relative unknown who ended up with the role: Laura Cayouette, who played Rocket in "Kill Bill: Volume 2," as well as more substantial roles in the Tarantino-produced "Daltry Calhoun" and "Hell Ride," and can be glimpsed at 2:02 in the trailer. She's got small roles on the way in "Abraham Lincoln: Vampire Hunter," "Loft" and "Now You See Me" too.
The gentleman at the end, at the 2:18 mark, who asks Django his name is another in-joke of a kind: the actor is the great Italian star Franco Nero. Best known for roles in films like "Camelot," "Die Hard 2" and "Letters To Juliet," he presumably came to Tarantino's attention as the lead in 1966's "Django," Sergio Corbucci's ultra-violent Western that's one of the key reference points for Tarantino's film (watch it in full right here). The plot was quite different -- in the original, Nero's Django is a drifter who carries a coffin containing a machine gun -- but it did involve revenge, with Django looking for Major Jackson, who killed his wife, so it's a nice tip of the hat to include a meeting of the two Djangos, even if Nero's role is relatively minor.
