The first official screening was on April 18th at the New York Comicon.
Both versions of the BloodRayne costume, the one you see on Vera to the left and the final version actually used in the film were both made by Vera's mother, a master seamstress, who created both costumes based on pictures Vera sent her by snail-mail and without a fitting. Mom was in New York and Vera was in Los Angeles.
