See How Under The Dome's Explosions Roared To Life

“Breaking Point” (Season 3, Episode 7 of Under The Dome) was explosive. A newly-healed Christine crawled out of her cocoon, the Kinship attempted to mine the amethysts, and the resistance blew the caves to pieces.

Check out these exclusive behind-the-scenes photos and insider stories—like how Christine’s pulsing purple wound was made. Click through to the end and read a special questionnaire from James C. Oliver, Assistant to the Executive Producer.

The material used to make the caves was flammable and a severe safety hazard, preventing the team from doing this stunt at full scale. To get the desired size and intensity of the explosion, Dave Beavis and his team built a mini model of the caves on set.

To allow camera access into the cocoon cave set, one of the walls needed to be removed. When taken out of their intended environment, these cocoons may not look as threatening, but somehow manage to look just as gross.

Rick Pour in the Under The Dome makeup department created Christine's prosthetic wound and, with a little help from the VFX team, made it come alive in a pulsing purple.

Director Sam Hill and Dean Norris took a break to review the script on set while Episode Writer James C. Oliver stood by to answer questions.
