Goodman, Watanabe join Transformers
John Goodman and Ken Watanabe are to voice two new Autobots in the fourth Transformers film.
The pair will join voice actors Peter Cullen and Frank Welker in Transformers: Age Of Extinction.
John, who previously voiced characters in Cars, Monsters University and Monsters Inc, will lend his voice to Autobot Hound, while Ken will play Drift.
Peter is to reprise his renowned role as the voice of Optimus Prime, which he has played since the 80s cartoon series, with Frank taking on a new character, named Galvatron.
Director Michael Bay said: "I am pleased to welcome two gifted and versatile actors, John Goodman and Ken Watanabe, to the world of Transformers. And to re-team with Peter and Frank, who have brought Transformers characters alive from the beginning.
"I've been fortunate to work with some of the best voice talent in the business, and together we will introduce several exciting new robots to fans of the franchise around the world."
John DiMaggio, Mark Ryan, Robert Foxworth and Reno Wilson round out the voice-over cast - John and Mark will voice new characters Crosshairs and Lockdown respectively, while Robert reprises the role of Ratchet and Reno returns as Brains.
Mark Wahlberg, Stanley Tucci, Li Bingbing and Kelsey Grammer will star in the next instalment, which sees Optimus Prime and the Autobots joining forces with the humans to defeat a powerful new rival.
Emmy and Golden Globe winner John, who previously starred in George Clooney's The Monuments Men and the Coen brothers' Inside Llewyn Davis, is attached to star in Rupert Wyatt's crime drama The Gambler, where he would reunite with Mark.
Ken, who has starred in The Last Samurai and Inception, next stars in Gareth Edwards' Godzilla remake as Dr Serizawa, alongside Aaron Taylor-Johnson, Bryan Cranston and Elizabeth Olsen.
