When Iron Man was announced here at ILM the artists started knocking down my door asking to be assigned to the project. We are all thrilled at the opportunity to work on this film and equally excited for our new relationship with Marvel."

"This is also a great script, with new and challenging work, which is just the way we like it here," added Visual Effects Supervisor Ben Snow (Star Wars: Episode II, King Kong) who is heading up the ILM team with Oscar winning Animation Supervisor Hal Hickel (Pirates of the Caribbean 1, 2, 3).

Through this collaborative effort, we look forward to providing movie-goers the high-action, visually compelling entertainment they expect from the Marvel brand," said Kevin Feige, President of Production, Marvel Studios.

Marvel's SVP of Post Production, Charlie Davis elaborates, "The post production process on a movie of this scope is always very complex and having ILM create the Visual effects, Skywalker Sound design and mix the sound, and E-film digital color time the picture all in close proximity up in San Francisco is the best of all worlds come together."

Touting a new relationship with EFILM at the Ranch, Skywalker Sound's VP and general manager Glenn Kiser stated, "Because of EFILM's DI suite at the Ranch, our clients can now finish sound and picture at the same time under one roof. At Skywalker, we've always coupled the best creative talent with top technology, and we're looking forward to showing off our best work on Iron Man. We can't wait to have Jon Favreau and his team in the house." Multiple Oscar winner Chris Boyes (Lord of the Rings: The Return of the King, Titanic) will tackle sound design and the mix.
