Behind the scenes video clip from Benjamin Button

In this behind-the-scenes video clip, Brad Pitt and Cate Blanchett discuss with director David Fincher the special effects used to make Pitt look older. In The Curious Case of Benjamin Button, a loose adaptation of F Scott Fitzgerald's short story, the titular hero ages backwards. Using make-up and CGI effects, Pitt plays him at every stage in his unusual life.

We love Blanchett's cheeky line, "By then you would have had so much work done...". Visit official Benjamin Button movie site for more information. Remember, we analysed the trailer in our issue 177 last year. The film is released in the UK on 23 January 2009.
