Digital-shy Transformers director Bay tries 'new toy' 3D

Rosie Huntingdon-Whiteley helped change the feel of the 'Transformers' franchise and was a welcome addition to the cast, but director Michael Bay was more hesitant about moving into 3D.

British model Huntingdon-Whiteley replaced actress Megan Fox in the role of Carly in the action series franchise, and Bay has said she was a great choice because she brought a "spark" to the film.
