American actor and producer Mark Wahlberg has confirmed he is going to star in Transformers 4. The 41-year-old has revealed that he decided to accept a part in the movie after developing such a great working relationship with director Michael Bay on the set of their upcoming action comedy film Pain and Gain.

"Transformers came about because we had such a great time working together (on Pain and Gain). We kind of complemented each other throughout the entire process with what he does and what I do and what we were able to do together, and then after that I was like, 'Dude we gotta work together again,' and he was like, 'Well I got a project, you interested?'" contactmusic.com quoted Wahlberg as saying.
