"Veins" includes complex character transformations into monstrous creatures. Very early in the production, we chose to create the majority of these special effects on set with prosthetic makeup by the Avatar FX team, led by Bruno Gatien. This approach presented many challenges during filming and required great generosity from the actors. The result is so realistic and rich in emotion I felt the 'monsters' came alive on screen - in large part thanks to the live performances rendered in makeup.
