stars in that version would have been  Cate Blanchett (qv) as Agatha, Matt Damon (qv) as Witwer,  Ian McKellen (qv) as Burgess and Jenna Elfman (qv) as Lara  Anderton. After the delay, Javier Bardem (qv) has stated in  interviews that he was offered the part of Witwer, but turned it  down because he "didnt want to just run around chasing Tom Cruise".  This led to the casting of Colin Farrell (I) (qv).
