O8: No Expense Spared
Apparently, filming at The Met cost Ocean's Eight $1m. They could do with it since their deficit is $40m. Some nice pics in this article of some of the outfits. A few fans reckoned they could see RA all dressed up and appearing in that scene - I reckon that Corden's insurance agent has asked RA's character to keep an eye on the women at the fashion show because he is suspicious of them.
