Quentin Tarantino

With his latest film, director Quentin Tarantino was inspired both by spaghetti Westerns and the drama of slavery and the Civil War. The movie is extremely violent — but, says Tarantino, "What happened during slavery times is a thousand times worse. ... If you can't take it, you can't take it."

The British actor has over 100 acting credits, including the new film The Song of Names and the streaming TV series Tin Star. Roth also appeared in Reservoir Dogs, The Hateful Eight and Pulp Fiction.

Austrian actor Christoph Waltz won an Oscar for his portrayal of Nazi Jew hunter Hans Landa in Quentin Tarantino's 2009 film Inglorious Basterds. Teamed up with Tarantino again in Django Unchained, he says Tarantino's writing and the rhythm of the language speaks to him as a performer.

In the past year, actor Michael Fassbender has played a mutant villain in X-Men: First Class, psychoanalyst Carl Jung in A Dangerous Method, Mr. Rochester in Jane Eyre and a sex addict in Shame. He discusses several of those roles, as well as his part in Inglorious Basterds.
