Hi! I am Dean Wright, a Film Director, but used to be a Visual Effects Supervisor/Producer (The Lord of the Rings, Narnia, Titanic). AMA
Hey there, I've moved on to writing and directing movies now - in fact - my first film is opening in Mexico on Friday, 20 April and in the USA on 1 June (Mexico Title - CRISTIADA; USA Title - FOR GREATER GLORY), and it stars Andy Garcia... but I spent many years helping create visual effects for some of the biggest (and most challenging) films ever made. AMA.
Okay - got some work to do - promise to come back later and answer more for as long as I can! (Wow - curious about the down votes... what do they want?? Can't please everyone! :)
