James Cameronis mourning the death of a close friend and collaborator.

He produced great films, not by wielding power but by spreading warmth and the joy of making cinema.

He inspired us all to be and to bring our best, every day.

I have lost a dear friend, and my closest collaborator of 31 years.

A part of myself has been torn away, added Cameron.

Landau died on Friday after a 16-month battle with cancer.

I think Jim was a little skeptical.

He said, So I understand were gonna get to be pretty good friends.

Or maybe not,' he told Deadlines Pete Hammond on Behind the Lens with a laugh.

We did that sort of as a one-off, Landau recalled of joining Lightstorm.

And that worked, the relationship worked, and I think we built it up.
