A couple of days ago a rumor hit the internet saying that Mark Wahlberg was in talks with Michael Bay to join Transformers 4. Bay has now put this rumor to rest saying,
The Mark Wahlberg T4 rumor is just a rumor. Mark and I are talking about another film project.
So that's the end of that. I guess the news here is that Bay is already prepping up for another film project after he's done with his fourth Transformers movie, and he wants Wahlberg to star in it.
