No Guinevere in this story?

Àstrid Bergès-Frisbey was cast to play Guinevere back in 2014. http://www.hollywoodreporter.com/heat-vision/king-arthur-finds-guinevere-pirates-733876 According to Entertainment Weekly she'll be a mage in this retelling.

The mermaid from POTC 4 is playing her apparently.

What's missing in movies is same as in society: a good sense of work ethic and living up to ideals.
