I apologize, but it appears there isn't an actress named "Briana Shann" with a widely documented film career or significant roles that match your request. My searches have not yielded significant results for an actress with this name and a notable filmography that includes major films or a distinctive style for which she is known. There might be a typo in the name, or she might be a lesser-known actress than implied by the request. If you have a different name or more details, I would be happy to try to provide the biography.
