It's possible that:
* The name is spelled differently: Perhaps there's a slight variation in the spelling.
* It's an alias: The person may use a stage name or pseudonym.
* They are a less known figure: They might be a local actor or involved in independent projects.
To help me find information, could you provide any additional details about Erik Grey, like:
* Approximate age or birth year
* Any other known projects they might have worked on
* Any specific genres or roles they usually play
With more information, I can try to locate their filmography.
