It's possible:
* He's a lesser-known actor: He might have smaller roles in projects that haven't gained wide recognition.
* He's using a stage name: His real name might be different, making it harder to find his credits.
* He's a beginner: He might have just started his acting career and doesn't have a long filmography yet.
If you have more information about him, like a specific project he was in or a photo, it might be easier to find his credits.
