David Goyer Confirms 2 Other Monsters For Godzilla (2014)
In addition to Godzilla, David Goyer says, at a QnA over at Reddit, that while he was working on the movie, there were at least two other monsters featured.
Of course, things could have changed as Goyer notes that since he worked on Godzilla, a bunch of other writers have come after.
Re: Godzilla, I only did 4 weeks on it and there've been a ton of other writers that came after me. But I believe there will be other monsters, yes. There were at least 2 others when I was mucking about with it.
Gareth Edwards is currently filming Godzilla in Vancouver where we have already seen a plethora of set video and images.
We've seen the military involved as well as what appears to be nuclear missiles and devastation, though if Goyer's comments hold true, we don't know if they are from Godzilla or one of the other monsters.
Godzilla opens May 16, 2014 in 3D starring Aaron Johnson, Ken Watanabe, Elizabeth Olsen, Juliette Binoche, David Strathairn, and Bryan Cranston.
