I went on IMDB a while back and saw that Lee Pace was Basil Sandhurst/The Controller for the upcoming Guardians of the Galaxy film. I was also on Ophelia Lovibond's, but where it said Guardians of the Galaxy, she wasn't listed as 'The Collector's Aide', or anything at all. Where is the source for her being cast as that? Or is IMDB not a reliable source? Also, if it is reliable, should we change Lee Pace from To-Be-Confirmed Villian to Basil Sandhurst/The Controller?
