Does anyone know how Eskil Vogt and Joachim Trier split the writing of this film? Was it a long, fully integrated collaborative process, or did Vogt plot out the ideas and write the screenplay and then hand it over to Trier for editing?

The reason I ask is because, although I liked the film, it seemed exceedingly literary. It seemed as if the writer had finished the screenplay, said, "well, I've just written the most literary screenplay ever ... and all about the lives of writers and the details of the writing process, to boot" and then handed it over to the director, saying "make this cinematic for me." Then Trier went on to pull out every stylistic stop he could think of.

Obviously, since both Trier and Vogt are credited as writers, this isn't what happened. And I know, I know, IMDb credits Vogt with directing two shorts. But Alain Robbe-Grillet directed films as well, so I'm not sure that means anything.

Anyone know anything about this? Or, more broadly, anyone else think the film was really, really literary?
