Kerry Washington admits it was difficult filming Quentin Tarantino's new film, 'Django Unchained'.

The 35-year-old actress plays Broomhilda, a slave owned by wealthy baron Calvin Candie (Leonardo Dicaprio) who is separated from her husband Django (Jamie Foxx), in the spaghetti western film, and admits it was difficult to take on the part.

Speaking to BANG Showbiz at the UK premiere of the film in London's Leicester Square on Thursday night (10.01.13), she said: ''I found all of the scenes difficult. To wake up everyday and be told you're not fully human is a challenging thing to embody.''

The screen siren also revealed she had to fly her family to visit the film's set in order to relieve the emotional stress she endured while playing the downtrodden character, who is whipped at one point in the film.

She explained to the Daily Beast website: ''I needed all their support for this film because it was so mentally hard in many ways.

''It's so unthinkable that my ancestors endured all the torture and pain. I saw things in the script and thought this never happened. But then I talked to Quentin and he showed us the history books that illustrated the masks and other items used to inflict torture and violence on the slaves. It really blew my mind and made me appreciate even more what my ancestors made it through.

''I barely made it through pretending.''
