In 2008,Iron Mandebuted as the Marvel Cinematic Universes first film and its first blockbuster.

Years later, when he was pulling together Marvel Studios, he reached out to me to come in.

I met with them in their first offices on Beverly Boulevard above the Mercedes dealership.

IRON MAN

Zade Rosenthal/Marvel

It was a few people in a few offices.

It wasnt very glamorous at all.

Iron Manwas a relatively low-budget film.

Under those circumstances, it wasnt like you had your standard list of movie stars to choose from.

It was the first time I met with somebody where I understood how the movie would come together.

It wasnt an easy job to get him cast.

There was quite a bit of resistance at first.

But after he had filmed his screen test, the studio got excited.

Robert was a great beacon for other actors.

Gwyneth Paltrow came on board, and Jeff Bridges.

As we filmed it, I made sure that I left a lot of room for improvisation and spontaneity.

The action sequences required a lot of planning.

Robert was the person who never doubted for a second the outcome.

He predicted it months prior.

Marvel anticipated that it would be a hit, but of a much more modest box office number.

Robert actually called out what it would make, which was close to double what they were expecting.

I still very much feel part of that family.

Whats nice is seeing where they go.

Im really happy that this is still a relevant franchise.

I feel like a proud grandpa!
