How many people flocked to see Chris Evans in The Red Sea Diving Resort?
How many people flocked to see him, Daniel Craig, and Jamie Lee Curtis in a Rian Johnson written and directed film - Knives Out?
Well, approximately $312 million dollars worth - on a film that had an estimated budget of $40 million. Not Marvel money, but financially successful, clearly. Enough so that Netflix payed $450 million for the rights to the two sequels.
It looks like names are super-helpful in establishing brand/franchises, as sure as anything I'll see Knives Out 2.
