The final credits probably won't be nearly as comprehensive as i would hope, and most of the actors and roles mentioned in this thread will probably remain uncredited, but i would hope it would at least fill in a few of the important holes and gaps we have in our present cast list, so i'm very eager to see what it has to reveal
In the meantime, here are a few loose-ends and, for the sake of completion, confirmation of Douglas Gresham's cameo (hopefully we will also get some new information on further crew cameos later on - there were quite a few on both LWW and PC)
Douglas Gresham - Slave Buyer
Aslan's Country - Teaser: Douglas Gresham, C.S. Lewis's stepson and co-producer of the Narnia films, makes a cameo on the Lone Island as a slave buyer.
