It's possible that:
* The name is misspelled: Double-check the spelling to ensure it's correct.
* The person is not a prominent figure in the entertainment industry: If he's a less known actor, his credits may not be widely documented.
* He works behind the scenes: Perhaps he's involved in production, writing, or other roles that don't directly involve on-screen appearances.
To help me find more information, could you provide any additional details about Matthew Quartermaine?
For instance:
* Is there a particular project you're interested in?
* Do you know what type of work he does? (actor, director, writer, etc.)
* Do you have any other information about him? (age, hometown, etc.)
The more information you provide, the better chance I have of finding his projects.
