It's officially here - the unlikely box office mashup that is Barbienheimer (Barbie + Oppenheimer) hits theaters this weekend, and the movie theater chain AMC released some pretty interesting figures - over 40,000 of its Stubs rewards program members have pre-purchased tickets to see both movies on the same day. Some people are grabbing a meal in between the flicks, essentially making an entire day out of the double header as Oppenheimer alone is three hours long.

Most, notably the movie's narrator Helen Mirren has fantastic full frontal from her early years in showbiz. Plus Emma Mackey, who plays one of the many Barbies in Barbie, has some great recent nudity. Issa Raehas been a big presence on the Barbie press tour, but she pulled a Sarah Jessica Parker by not actually going nude in her sex-filled series, Insecure, sans a brief and dark ass shot.
