It's no secret that "Ghostbusters 3" movie is in the works, however details about who will be in included in the cast are scarce.

However, hackers of Sony Pictures who've identified themselves as "Guardians of Peace" have leaked another email from the giant studio company revealing major information about the upcoming sequel-reboot.

A report from Independent UK claims that another set of leaked emails from Sony execs and Paul Feig says that the director is eyeing on "Game of Thrones" star Peter Dinklage as the new villain in the upcoming "Ghostbusters 3" movie.

The 45-year-old actor is said to be the "ideal" star to play the character of a convicted murderer who died after being hit by "supercharged electrical storm" and eventually turns into a ghost.

Meanwhile, more details about the "Ghostbusters 3" movie cast have leaked online. In an email dated October 8, 2014 discovered by The Daily Beast, Sony Pictures' controversial chairwoman Amy Pascal sent out a message to the original director and producer of "Ghostbusters," Ivan Reitman revealing her plans for the upcoming project.

"Agree that everyone is way too nervous about how this issue and how we present it but it isn't a sequel to the 80s movies and it is gonna be totally original with completely different characters and our job is to find a clever way to connect the movie to the original franchise so that we can use all the assets and everything that is great about the original franchise," the email read. "Paul's movie is gonna be the first one and from what I'm hearing Jennifer Lawrence and Emma stone and Melissa McCarthy and Amy Schumer and Liszzy [Lizzy] Kaplan just to name a few have already said they wanted to be in...."

It has been previously reported that the upcoming "Ghostbusters 3" movie will be an all-female cast thus, the actors being linked to the project are all women.

However, the leaked email exchange from Ilene Feldman, talent manager of Ryan Gosling, Amy Pascal and Michael De Luca, co-president of productions for Columbia Pictures dated October 3, 2014, claims that director Paul Feig is looking into casting one male role for the film.

"Ryan absolutely loved you. Said it was like speed dating because he was late after hitting every wrong gate on the lot. Not it should turn to marriage. He really wants to do something with you," Feldman told Pascal.

Pascal forwarded the message to De Luca asking what project Gosling is referring to, to which he replied, "It's Ghostbusters according to Ilene."

Then, Pascal emailed Hannah Minghella, the other co-president of productions for Columbia Pictures saying,

"There is one make [male] part paul is planning. How insane would that be... He also wants jennifer [Lawrence] and Emma [Stone]."

While, these revelations are rather exciting it should be noted that "Ghostbusters 3" is still in its early stages of development, thus nothing is final until the studio company would officially release the list of cast included in the line up.
