For the movie Infinite, I was tasked with designing the extremity of the Dethroner Bullet, which had to merge seamlessly with the main prop.
This metal and crystal device contained a nano-virus capable of imprisoning the mind of a Infinite, thus preventing his reincarnation.
The director wanted something that looked complex, partly organic and that had elements of a pinecone in its design.
Tasks like these are fascinating.
I also briefly worked on the Doomsday egg, and the destruction of Central Park.
