When did John Grey - screenwriter die?

There is no screenwriter named John Grey listed in any major film or television databases. It's possible there may be a less well-known screenwriter by that name, or there may be a typo in the name.

To help me find the screenwriter you're looking for, could you please provide more information? For example:

* Do you know any of his works?

* Do you know his full name?

* Do you know any other details about him, like his nationality or approximate year of birth?

With more information, I can assist you in finding the correct screenwriter.
