Transformers 4 director Michael Bay will not return for the next instalmentParamount Pictures

Even though Transformers 4 created box office magic, the future of the fifth sequel of the live action thriller movie is still uncertain as director Michael Bay and actor Mark Wahlberg will not return for Transformers 5.

In the fourth sequel, Transformers: Age of Extinction, Optimus Prime zooms into the outer space in order to find the Creators.

But without Bay at the directorial helm, it may become quite a task for the movie producers to maintain the momentum of the plot.

Inquisitr suspects that Bay's exit may bring some freshness to the fifth movie; however, it speculates that the movie may face problems with the lead actor's exit.

The Lone Survivor star, who portrayed the character of a mechanic and a father of a teen girl, got appreciation for his performance, though he had no much chances to prove his acting skills.

Movie Pilot reports that the upcoming movie may feature Megan Fox as the lead as the movie director is leaving the franchise and she is the only familiar face to fill the vacuum left by Shia LaBeouf and Wahlberg.

Fox was sacked from Transformers 3 after she reportedly compared director Bay with Hitler.

The Teenage Mutant Ninja Turtles star is reportedly excited to star in the highest grossing Hollywood franchise.

The plot of Transformers 5 is rumoured to be based on Optimus Prime's journey to the outer space to find the Creators while the Autobots continues to stay on earth in order to protect humans from Galvatron's evil destructive plans.

According to a report by Inquisitr, in order to have a leader in the absence of leader Optimus, Hot Rod will be turned into Rodimus Prime by infusing the Matrix left by the Autobot leader.

In the upcoming movie, the fight between the Autobots and the Decepticons may reach beyond space.

The production house of the movie, however, is yet to clarify the rumours about the casting, direction and plot of the movie.

The movie is expected to release in 2016.
