How they made Costa Verde explode

Heroes' visual effects team discuss

The city of Costa Verde blew up four years in the future in 'I Am Become Death' as a result of Sylar exploding. The visual effects team discuss the thoughts behind the explosion shots in episode four.

And if you've got a burning question about a Heroes episode that has already aired, post it on the Backstage Q&A board, and our backstage mole will do their very best to answer it.

 

Coming soon: Meet the Vortex man.
