It's possible:
* The name is spelled incorrectly. If you can double-check the spelling, it may help locate the correct person.
* The person is not a well-known actor. You may be able to find more information on IMDb or other movie databases.
* The person may be using a stage name. If you have any additional information about them (like their real name, birthplace, etc.), it may be easier to find their projects.
Please provide more information if you can, and I will do my best to help!
