English language???

It seems to be. I was just at the exhibit of the movie props at the subway station in Syntagma Square (Athens) and they had clips of the movie playing. It was all in English with Greek subtitles.

It's mainly in english also contains greek and spanish.

That's right... Most of it is in English (even from most of the Greek actors), with Greek subtitles. There is some Greek spoken though and some Spanish...

Thank you for your replies. As you all said it was mainly in english and can be seen and understood without knowing greek or spanish.
