, I agree with the Prod of Courtney Eaton.  Not really any refs about her.  The movie is a year away and she is not the title character.  There is more info about Oxenbould and he is the title character in the upcoming Disney film.  I'm not say a Disney film is more important or better than others, just they have a publicity machine.
S. Craig Zahler is more difficult.  The Prod states he has only written one screenplay.  While that is true, it is not necessarily a reason for deletion.  There are more references about Zhaler that might make him notable.  
Personally, I don't see Eaton passing an AfD, so let it be deleted.  I'd contest the Prod on Zahler.
