Cameo Role For Dench On 'Pirates..Stranger Tides' Movie?

Director Rob Marshall has apparently asked Dame Judi Dench to play a cameo role in which Captain Jack Sparrow (Johnny Depp) escaped into a carriage with a noblewoman (the role played by Dench) - Latino Review reports.

 The fourth Pirate film has Sparrow and Barbossa sailing to find the Fountain of Youth together, but encounters a new enemy with Blackbeard (played by Ian McShane).



I wonder how Marshall managed to get Dench on board?

I guess money talks? :)
