I can't believe that people doubted that Charlie Vickers could pull off the Halbrand is Sauron reveal, that he wasn't handsome or charismatic enough.
He was perfect, the way his demeanor changed as soon as Galadriel pointed out that there was no King of the Southlands. The way you knew instantly that he was truly powerful, instead of some lowly human. The manipulative sweet way he'd talk to Galadriel, trying to convince her to choose him. The rage in his eyes when she refused, his words becoming sharper.
I hope this is the form Sauron keeps for the rest of the show idc
