Smith began his career in London, where he worked at SVC Television, the editing and effects house Framestore and post house VTR, where he established his own 3D department. Immediately prior to joining PDI/DreamWorks, Smith served at The Mill as the CG supervisor on commercial projects for Nike, Honda, Volvo and VW Polo. He was a pioneer in the field of pre-visualization, and used that skill set to create PDI's layout department, which became an integral part of PDI's filmmaking process. Smith was also instrumental in helping to set up CG layout department for Aardman Animation for the production of Chicken Run. Known for his work on the award-winning pop video Go West for the Pet Shop Boys, Smith also received the first ever Gold Leaf Award for his 3D directorial work on the commercial West Lites.
