We shot in seven countries, all over the place, with a massive cast and huge set pieces.

Theres no question, its the most ambitious film weve made.

The director also reveals that Washington is very much the hero ofTenet.

[Laughs] This guy moves.

Speaking of vehicles, Washington recalls the difficulty of looking at ease while shooting a boat-set sequence with Debicki.

I was terrified, but when Christopher Nolan yelled Action!

I had to throw all that away and make it look cool, says the actor.

Why was he terrified?

Because its a boat, man!

Washington adds with a laugh.

I dont know how to drive a boat!

But I had to act like I did.
