Transformers: The Last Knight is a 2017 American science-fiction action film based on the Transformers toy line. It is the fifth installment of the live-action Transformers film series and a sequel to 2014's Age of Extinction. Like its predecessors, the film is directed by Michael Bay, and features Mark Wahlberg returning from Age of Extinction, with Josh Duhamel, John Turturro, and Glenn Morshower reprising their roles from the first three films, as well as Laura Haddock, Isabela Moner, Jerrod Carmichael, Santiago Cabrera, and Sir Anthony Hopkins all joining the cast.
The film premiered at Odeon Leicester Square in London on June 18, 2017, and was theatrically released in the United States on June 21, 2017, by Paramount Pictures in 2D, 3D and IMAX 3D. The film was met with an unfavorable reception from critics and, with an approval rating of 16% on Rotten Tomatoes, it is the worst-reviewed film of the Transformers series. At the 38th Golden Raspberry Awards, it was nominated for ten awards, including Worst Picture, Worst Director and Worst Actor for Wahlberg, but did not win any. Despite grossing $605 million worldwide over a budget of $260 million, it was considered a box office disappointment, reportedly losing the studio over $100 million. Critics panned the film's direction, plot, narrative, script, humor, pacing, lack of screen time of certain characters, and format changes. Positive mentions were given to the performances of Wahlberg, Moner, Hopkins and Cullen, as well as the musical score, action and effects.
A spin-off/prequel titled Bumblebee was released on December 21, 2018.
