Transformers: Age of Extinction (live-action movie)

Despite being a continuation of the first three Transformers films, none of the original human characters returned in this film.

Despite being co-produced by two Chinese film studios, the film's action scenes were not shot in China. Instead, parts of Detroit, MI, and Chicago, IL, were used as stand-ins for Hong Kong and China, respectively. This resulted in a scene error where the Willis Tower can be seen in the background of one camera angle of the Hong Kong battle scene.

Filming in Texas was delayed after a fire broke out in the house that was used during shooting.

Optimus Prime's alternate mode in this film is a customized Western Star 4900 SB truck. The design pays homage to Prime's G2 mode (where he was a 1995 Western Star 4964EX tanker truck) and Transformers Prime mode (where he took on the alternate mode of a military truck).

Isabelle Cornish, Margaret Qualley and Gabriella Wilde auditioned for the daughter role before Nicola Peltz was cast.

Landon Liboiron, Luke Grimes, Luke Mitchell, Hunter Parrish and Brenton Thwaites auditioned for the daughter's boyfriend role before the role went to Jack Reynor.

The story is set to take place four years after the final battle in Chicago, from "Transformers: Dark of the Moon".

Paramount Pictures entered an agreement with teaming with the Chinese film companies China Movie Channel and Jiaflix Enterprises upon the production of this film. This is the second Chinese co-production Paramount Pictures made after Iron Man 3.

Dwayne Johnson was offered the role of Flynn Vincent, but he declined due to scheduling conflicts with his movie Hercules: The Thracian Wars.

Bumblebee's alternate mode in this film is a 1967 Chevrolet Camaro SS automobile for some of the film then later a 2014 Chevrolet Camaro concept.

Drift's original alternate mode was a Nissan Silvia 615 sports car, but this was revised to a Bugatti Veyron Grand Sport Vitesse sportscar.

Hound's original alternate mode in The Transformers was a Mitsubishi J59 Military Jeep, but this was revised to an Oshkosh Defense MTV (Medium Tactical Vehicle) truck.

Mark Wahlberg asked that his children Ella Rae, Michael Robert, Brendan Joseph and Grace Margaret get roles in the film since they're "Transformers" fans.

Lockdown's original alt mode in Transformers: Animated was a customized muscle car, but this was revised to a Lamborghini Aventador LP700-4.

The black off-road sports cars used by the Cemetery Wind unit are Rally Fighters, which are limited-production cars manufactured by Local Motors.

Transformers: Age of Extinction shattered the box-office records of its predecessors, with worldwide earnings of US$400 million in six days, US$500 million in 10 days, and US$600 million in 12 days. And with a Rotten Tomatoes rating of 18%, it is the worst-reviewed film to earn over US$1 billion.

The steamships Columbia and Ste. Claire were partially restored for the scene where Lockdown and Cemetery Wind attack Ratchet.

Frank Welker reprised his role as Galvatron from the original G1 series after Hugo Weaving declined to return to the series.

The film was heavily panned not only for its incoherent storyline and ridiculously long running time, but also for blatant product placements involving western and Chinese brands. In addition, the film was criticized for 17-year-old Tessa's romantic relationship with 20-year-old Shane, and Shane using the "Romeo and Juliet law" as an excuse for their relationship. Critics also pointed out the film's sense of patriotism towards China.
