Michael Bay has denied having talks with Paramount and Hasbro about his future involvement in TF4. Here is what he said:
I am currently not talking to Paramount on T4 and T5 despite reports. I'm
looking at a lot of possibilities coming my way right now weighing options. Most
likely going to be doing the low budget Pain and Gain, a true story crime
thriller. It's a very quick shoot and quite funny. Also just finishing the 3
disc set of the Transformer trilogy.
Jason Statham has also denied reports that he will be involved in TF4, although he did not say that he wouldn't want to be in it.
