In a post over on his official message board, Don Murphy comments on one of the reasons behind why there has been little news on the expected Transformers Movie 2 film and how it relates to an expected strike in May 2008.
"For those of you most anxious about TRANSFORMERS 2, the silence you
hear is primarily because people are fretting about a presumed strike
in June 2008. Will it happen? I don’t know- does the public care about
strikes anymore in this day and age? What do rich people have to strike
about anyway? I don’t have any side here ( you hear about the writers
and the Producers but that actually means the STUDIOS) I just think
stopping work is kind of pointless. But since no one wants to be
filming IF a strike happens, everything needs to be done filming by the
end of May 2008. So this is affecting the lack of news about
Transformers 2 at least for now. Stay tuned."
