It's possible that:
* The name is misspelled: Could you double-check the spelling?
* The actor is less known: They might be a less prominent figure, working in smaller productions or local projects.
* The actor works under a different name: Perhaps they use a stage name or have a different name that they go by professionally.
To help me find the information you're looking for, could you provide any additional details:
* Nationality: Where is the actor from?
* Genre of work: What kind of movies or television shows do they typically appear in?
* Any specific roles: Do you remember any specific characters or movies they've been in?
