Every instalment of Michael Bay's Transformers movie franchise has always been an undeniable box-office hit. Since the first Transformers movie was released last June 28, 2007, three sequels have been produced for the franchise and all of them have been commercial successes. Unsurprisingly, a fifth movie to round up the franchise has been ordered and just recently, details about the upcoming film have surfaced.

Michael Bay has previously denied involvement in "Transformers 5." However, in an interview with USA Today, he revealed that he still has a lot of ideas for the franchise saying:

"There's kind of a new chapter, a new direction in movies I want to make. I have a lot of stories to tell. And it's about flexing new muscles."

Elsewhere, it is reported that several people who worked for award winning features like "The Walking Dead," "Lost," and "Iron Man" have been tapped to create the screenplay for the upcoming "Transformers" instalment. The list includes Andrew Barrer, Gabriel Ferreri, Akiva Goldsman, Matt Holloway, Robert Kirkman, Art Marcum, Zak Penn and Jeff Pinker.

Transformers 5 is rumoured to have at least 2 story lines. The first story will take place here on Earth and will likely follow the events of the life of Cade Yeager played by Mark Wahlberg. According to the speculations, he would be teaming up with the Autobots and Dinobots in order to save the world from threats. On the other hand, the second story will focus on the Leader of the Autobots, Optimus Prime who will be searching for his lost ancestors in space. His ancestors, the Quintessons are the ones who created Optimus Prime.

A new villain reportedly named, Unicorn, is also expected to be introduced into the series. Unicorn is a giant transformer and because of its sheer scale the battle between him and the Autobots cannot take place on Earth. The two sides would come head to head in space as such the upcoming movie might do away with the human story line all together.

"Transformers 5" is scheduled to be released on 2017.
