Bueno, mayormente habla huevadas, pero lo interesante es esta parte:

Crave Online: This being your first “effects” movie, was it difficult or strange acting in that environment?

Tyrese: Actually, as difficult as it appeared to be it was pretty regular within all of that difficult shit. It’s not like they said put this green suit on and stand there like Tickle Me Elmo. It was the surroundings. It was about 40-50 foot Transformers in front of us that they built.

Crave Online: So they are not just using CGI.

Tyrese: No, they had about five real Transformers. Bumblebee, Optimus Prime was real. It was a gang of [them], they had Megatron.

O sea que aparte del Bumblebee real que hemos visto ya en fotos, habría otros 4 Transformers "de carne y hueso"! O por lo menos armados en parte, porque tambien se conocen las piernas de Megatron construidas.
