Although Lena Heady is best known for her portrayal of Game of Thrones' villainous Cersei Lannister, her newest television role in Beacon 23 is the perfect follow up, that will both put Heady back in the spotlight and allow her strengths to shine through. For eight seasons, Heady portrayed the sometimes villain, sometimes hero Cersei Lannister. Though Heady was already well-established as an actor before Game of Thrones, her role as Cersei remains iconic, despite the series ending in 2019. Arguably, it is now what she is best known for.
