The note for an Adam Sandler movie asked actresses to "understand the context" of their scenes and wear a "form fitting tank" to show off their cleavage.
"There's like 'dickery' as I call it [in Hollywood], where they're stuck in this Mad Men / Entourage era and it's just boring and it's kind of embarrassing," she explained to Nylon.
"It's old-fashioned and it's like, face palm, it's like, that's not what's going on now in the world, you've gotta change. If film is our number one export, be careful with what we're putting out there because you can do a lot of damage."
The actress - who was fired by her agent following the call out - added that she wants "to promote thinking a little bit".

What to Read Next
"I think for all 10% a little bit deeper, a little bit funnier - a little bit more thinking, a little bit more feeling - the world would actually change. And Hollywood used to be at the forefront of that."
She continued: "Hollywood is accused all the time by people, 'Liberal Media! They have an agenda!' And you're goddamn right I have an agenda. I have an agenda for people to be better humans.
"Why? Because I want more people to talk to, more people to play with, and more interesting things to watch, listen to, and read. It's not that complicated."
