When it comes to Steve Buscemi and Sienna Miller in "Interview", I don't think I've seen a middle aged man and a young woman that had this much chemistry since Bill Murray and Scarlett Johanson in "Lost in Translation". However, if Murray and Johanson's on-screen relationship was warm and nurturing, the relationship between Buscemi's Pierre and Miller's Katya is more like a cage match.
Pierre, a self-important political journalist, is assigned to do an interview with a subject he believes to be beneath him ... Katya, a schlock TV/film actress and tabloid fixture. The two characters clash instantly, but end up continuing the "interview" all night in Katya's opulent New York loft, where the two characters ridicule, antagonize, manipulate, charm, seduce and abuse one another, both for their own career agendas and to satisfy their equally inflated egos. Steve Buscemi (clearly a talented director as well as being a great character actor) and Sienna Miller both give terrific performances playing these two complex, layered and often repugnant characters. I found the whole thing fascinating.
Toward the end of the film Pierre tells Katya "What do we both have in common? Neither of us believes in relationships. There's no equality ... there's always a winner and a loser." Watch the film to see which is which.
