 Several actresses were considered for the role of Becky. Among them  were Sarah Silverman (qv) (who didnt want to play a love  interest, but noting that she would have played Randal in a  heartbeat), Rachel Weisz (qv) (who the filmmakers considered too  difficult to get hold of), Bryce Dallas Howard (qv) (who was  already, albeit secretly, attached to  _Lady in the Water (2006)_ (qv)), Liv Tyler (qv) (who did not feel  comfortable saying much of the dialog), and Ellen Pompeo (qv) (who  could not do the movie because of her commitment to  _"Greys Anatomy" (2005)_ (qv)). Rosario Dawson (qv), considered a  long shot, finally agreed to do the movie, mainly to see the filming  of the donkey show.
