I was the VFX Supervisor and Lead Compositor on this project.  We took a number of green screen plates and combined them utilizing Nuke X and After Effects.  We then built a custom CG Background and added the additional FX.  Additional VFX work by James Pina @Boundary VFX.  @Moving-Box Studios, 2015.  Directed by Joe Zohar.  http://www.movingboxstudios.com
