Transformers: Age of Extinction (2014) 

Transformers: Age of Extinction (or simply Transformers 4) is a 2014 American-Chinese science fiction action film based on the Transformers franchise. It is the fourth installment of the live-action Transformers film series and the final installment for Michael Bay to direct and stars Mark Wahlberg in the lead role. It is both a sequel to 2011's Dark of the Moon and a soft reboot of the franchise, the film takes place five years later, after the Decepticon invasion of Chicago. Like its predecessors, the film is directed by Michael Bay and executive produced by Steven Spielberg. Ehren Kruger is the film's screenwriter, having written every Transformers film since Revenge of the Fallen. The film features an entirely new cast of human characters and is the first in the series to feature the Dinobots. Returning Transformers include Optimus Prime, Bumblebee, Ratchet, Leadfoot, Brains, and Megatron (now known as Galvatron). The film was released on June 27, 2014, in IMAX and 3D.

Transformers: Age of Extinction (2014):
1. Galvatron in this film is based on his original version from The Transformers: The Movie (1986) (Megatron resurrected as a minion, who eventually rebels and returns to leading the Decepticons) and Nemesis Prime from Transformers Prime (2010) (a human-built duplicate of Optimus Prime). His black color scheme is also a homage to the The Transformers (1984) Decepticon Motormaster, an Earth-built clone/rival of Optimus Prime.

2. Ratchet appears to have already known Lockdown prior to the movie's events. This could be a reference to the online Cyber Missions episodes, which took place between Transformers (2007) and Transformers: Revenge of the Fallen (2009) and featured Ratchet and Lockdown fighting against each other (itself a homage to Transformers: Animated (2007)).

3. Optimus Prime's alternate mode in this film is a cab-over truck and later a customized Western Star 4900 SB truck. The cab-over truck is a homage to Optimus Prime's original alternate mode in The Transformers (1984); and the tanker truck pays homage to Prime's G2 mode (where he was a 1995 Western Star 4964EX tanker truck) and Transformers Prime (2010) mode (where he took on the alternate mode of a military truck).

4. At the end of the film, Optimus Prime leaves Earth to embark on a quest to find the creators of the Transformers. This was one of the originally proposed ideas for the plot of The Transformers: The Movie (1986) that was rejected for unknown reasons.
