Don't know if its a mere coincidence that Charlie Vickers has been recently casted in exactly the same roles recently. Rings Of Power :Halbrand/Sauron/Annatar and then Lost Flowers of Alice Hart: Clem Hart
See how the plot of both these shows is basically just the same for Charlie's characters.
Intimidated and unknowingly inspired by a darker character and finds refuge with other victims of that dark person, closely observing them.
Amazing skills of craftsmanship , stunning looks , a greatly charismatic & charming personality ,a way with words and subtle rage fits that manifest over time.
Intends to make things right and sometimes surprisingly heroic actions but makes harmful transgressions, has secret selfish pursuits compromising the wellbeing of others around him and conflicts with those who oppose him finally isolating himself.
Keeps oppressing the weak and flees judgement . Controls the will of others and seeks even more control.
Finally defeated by his victims but the scars of his oppression affect his victims deeply , taking a huge time to heal from the trauma he gave, while some never even healed.
Fantasy world: Sauron
Real World: Clem Hart
Hope to see Charlie Vickers next in a role that won't be dark. Hope it will settle the stubborn desire to see more of romance between Halbrand & Galadriel ;)
