Now Fonda says those slaps were even harsher than they looked.
The thing that comes to mind right away is we have a slapping scene.
I slap her, she slaps me, Fonda toldBarrymore.
“Well, Jenniferas per Jennifershe had this enormous diamond ring.
After a bit of a pause, Fonda added, Shes never apologized.
We talked about how we were going to do this over and over again.
I was so afraid of her and she was so brazen and like, Just hit me!
Dont worry about it, its gonna be fine!
Lopez remembered the scene taking on a life of its own.
I just remember afterward Jane had a blood blister right at the top of her eye.
My nail, like, went up into her eye, Lopez said.
I was, Oh, Im so sorry, and she was like, Its fine, its fine!
Lopez added, She didnt care.
Shes such a gangster bitch.
I just love her.
