Harry Potter and the curse of the screaming groupies

the Daily Mail: "Things got so bad after Saturday's preview that the police were called - more than 450 screaming fans had trapped cast members inside. While security staff managed to muscle Radcliffe to his car, Jenny Agutter and Richard Griffiths were forced to escape through a window. As producer David Pugh points out, this was no easy manoeuvre for the well-upholstered Griffiths: 'You try and get Richard Griffiths out of a back window. It was a bit touch and go.'"
