While the cast is starting to come together for Transformers 4, with Mark Wahlberg, Nicola Peltz, and Brenton Thwaites recently joining the sequel, there is still little we know about the story. Today, we have word that a recent screenplay draft for the sequel has leaked, revealing that Unicron is the main villain. However, director Michael Bay himself took to his official website to reveal that this is not an official screenplay for Transformers 4. Take a look at what the filmmaker had to say.

"Some Internet sites this morning reported that some document recovery guy has found a legitimate 120 page script of Transformers 4. I can absolutely 100 percent say this is completely false. The only two people in the world that have our unfinished script are Ehren Kruger and myself. Also we are only up to page 70 in our T4 script. Maybe this guy has a cartoon or something else - but definitely not our movie!

Bay"

According to the director, everything that follows is not indicative of what Transformers 4 will become. However, this is not the first time the filmmaker has reacted to a leaked script. The director revealed in September that the Ninja Turtles leaked script by André Nemec and Josh Appelbaum wasn't being used for the movie anymore. However, in November, Kevin Eastman's comments seemed to indicate that the writers are still working on the movie, so it is possible that the leaked script is still being used. With that in mind, take a look at the details from the Transformers 4 screenplay, which may or may not be legit.

The story takes place four years after Transformers: Dark of the Moon, which confirms an earlier report from November about the time frame of this sequel. The movie starts with a new global crisis in the form of a massive "space ball" descending towards Earth, which is discovered to be a ship which Unicron is aboard. While the Autobots try to contend with Unicron, the villain's cronies lead by Galvatron attack a government base in Colorado which houses Decepticons such as Megatron, along with an array of Cybertronian Earth weapons. After the base is destroyed, a female survivor known as Josie initiates a bizarre process that turns her into a transformer known as Circuit Breaker.

Unicron was first introduced in the 1986 animated movie The Transformers: The Movie, as a transformer who can change into a mechanical planet. This evil entity often uses the Decepticons to carry out his nefarious plans, which seems to fall in line with this story line. After Unicron destroys the Colorado base, he downloads the memories of all the Decepticons, including Megatron.

The script features new transformers such as Vector Prime, guardian of Primus, the one being that can stop the destruction of the Transformers' home planet, and even a few Dinobots. The screenplay was reportedly last revised on November 30. Since production will not begin until sometime next year, these details may change between now and then.
