Apparently this foreign born A+ list mostly movie actor not named Ryan Reynolds (because it applies to almost every cast member he was ever worked with) does not get along at all with his foreign born recent co-star.
They are doing press and it is ice cold. It is Dakota/Jamie first press tour cold.
Apparently our actor thought the actress would be interested in joining his ever expanding harem during filming.
He was wrong and she was not happy.
It has carried over.
