Robyn Snodgrass

VP of Ultra Productions

EFX are our “go to” guys for all of our crazy stunt/production builds! If we can think it up, they can find a way to make it happen. EFX has helped us hang aerial dancers  from the top of Los Angeles City Hall for the film La La Land, built our precision decks to fly 300 light drones over Dodger Stadium for Wonder Woman and they restored and “shipwrecked” a 10,000 pound pirate ship for a Pirates of the Caribbean promotional stunt on the beach by the Santa Monica pier. We have been all over the country with them. From the many projects at Comic Con in San Diego to air shows throughout the U.S. to the Today show in N.Y.C. The list goes on! EFX has the talent & incredible work ethic & professionalism to get it done! They have been the only team for us for years now and you won’t find a more dedicated group of professionals to bring your ideas to life!
