The fourth film in this franchise was directed by Michael Bay but features an entirely new cast that include Mark Wahlberg, Kelsey Grammer, Stanley Tucci, Nicola Peltz, Jack Reynor, Li Bingbing, TJ Miller & Sophia Myles. Peter Cullen also returns as the voice of “Optimus Prime” and he also is joined by a new cast that include John Goodman, Ken Watanabe, Mark Ryan, John DiMaggio & Frank Welker. Welker voiced “Megatron” in the 1980s animated series and the 1986 animated film. This film takes place 3 years after the previous film and now the CIA has issued a Black Op mission to wipe out the remaining transformers, both good and bad. Optimus Prime is on run but is found and restored by a crackpot inventor from Texas. The inventor and his family become targets of the CIA while Optimus becomes a target for a Cybertronian bounty hunter. Despite this film being the highest grossing film of the year, it was yet again panned by critics for bland storylines, uninteresting characters and over reliance on big action sequences.
