Fans will be hoping to catch a glimpse of sex symbol Brad Pitt as he starts filming today (Monday) at the former Oxford Prison.

But the set of the new spy thriller, Spy Game, will be closely guarded and staff at Universal Studios are keeping his movements secret.

The former prison has been altered with banners and Chinese men in Oxford have been asked to play extras. Mr Pitt is expected to be filming for two days. Reports that he is staying at the Randolph Hotel have been denied.
