the odyssey is projected to gross atleast 1.3bn$ and chris and emma nolan together will get paid 20% of the box office upfront before the studio makes money out of it. that means 260mn$. this kind of deal exists mainly for actors whose face value drives ticket sales like Tom Cruise, RDJ

the face value of actors works in movies and actors get paid for that

BUT christopher nolan is and will be the only exception., the branding associated with his name is the moat not the actors
