The writer took to Twitter yesterday (June 9) to initially register his interest in the project.
"I'm putting myself out there to write the movie adaptation of Fifty Shades of Grey..." he posted.
This was followed by a message claiming that he had enquired about the possibility of writing the screenplay.
"Contacted my agent about adapting Fifty Shades of Grey and have heard nothing back," he said. "But it's a Saturday and Gay Pride, so: understandable."
After a number of his followers rubbished the idea, Easton Ellis tweeted again, emphasising that he was serious.
"Completely committed to adapting Fifty Shades of Grey. This is not a joke," he said.
"Christian Grey and Ana: potentially great cinematic characters."
This morning, the writer was clearly still thinking about the project and posted the update: "Hope E.L. James doesn't think I'm being a prankster. I really want to adapt her novels for the screen. Christian Grey is a writer's dream..."
Angelina Jolie was previously linked with the Fifty Shades of Grey film adaptation, but has denied reports that she has discussed directing the feature.
Easton Ellis is best known for his third novel American Psycho, but more recently he has ventured into film, writing the screenplay for an adaptation of his short story collection The Informers (2008) and thriller The Canyons (currently in production).
