Sam and I started working together when I was in my mid-20s, Shyamalan said.

He taught me that the culture of a set comes from the top down.

He led with kindness and showed me how to navigate pressure with grace.

He made me laugh and took care of me at the same time.

He did this with everyone.

When he was around, that was always true.

Working for Sam changed the entire trajectory of my life, Staub said in a statement.

He showed me how filmmaking could be a transformative experience for a crew and not just a job.

Along with his wife, Mercer is survived by his son Miles and daughter Sierra.

A memorial service will be held in the fall.
