There are also roles for 'Hunger Games' star Stanley Tucci, Peter Cullen, who will once again voice Optimus Prime, and Glenn Morshower, playing General Morshower.

And as the casting notices for extras were also posted in Austin as well as Los Angeles, it's thought some of the film will be shot in Texas too.

Director Michael Bay's film, being a Chinese co-production, will also be heading to the Far East for shooting too.

It was recently announced that four roles for Chinese stars will be allocated via a reality TV talent show.

It's due out in June, 2014.
