Bankman-Fried typically appears disheveled, with his curly hair looking like he just rolled out of bed. So the curls are essential for nailing the look.
I had that in mind when thinking about which actor could play Bankman-Fried. Such names like Timothée Chalamet and Alex Wolff popped up, but they didn't quite fit the mold.
I'm picking Harry Melling, who, at a young age, nailed being a terrible person as Dudley Dursley in the "Harry Potter" movies. More recently he's made appearances in "The Queen's Gambit" and the new Netflix movie "The Pale Blue Eye."
He'd have to hide the English accent, but I have confidence that he could channel SBF's often awkward energy.
