MCU: Casting The Remaining (Relevant) Asgardians
2. Angela - Clémence Poésy
In the highly unlikely event that the MCU intorduces Thor and Loki's other sister (this one being from Marvel's version of Heaven, called Heven, instead of Hell, like Ragnarok's Hela), then this former Harry Potter star would be more than worthy a choice.
Clémence Poésy hasn't exactly got the busiest of schedules, with her main appearances since her visit to the wizarding world being in the British-French drama The Tunnel, meaning that a foray into the MCU wouldn't be too hard to arrange from a scheduling standpoint.
Speaking of The Tunnel, Poésy has proven her acting abilities over the course of its seasons, yet is still relatively unknown, much like the majority of the cast of the Avengers when they first took up their current roles. It makes her the perfect fit to play this superhero, especially with Asgard due a rebuild after Ragnarok.
