Actors/actresses you wish would un-retire

Yesterday the truly bummer news was announced that Bruce Willis would be stepping away from acting due to his aphasia diagnosis:

This got me thinking about other stars who have stepped away from the industry, for a plethora of reasons. While Willis is unlikely to return (understandably so) are there certain actors or actresses you wish would come back to Hollywood?

For me it's Daniel Day-Lewis (easy answer, I know) and Cameron Diaz (who truly crushed it in underrated roles like In Her Shoes). Who would you like to see make a full-time comeback?
