I'd rather have Liam Neeson as current old Strange with Joseph Gordon Levitt playing flashback scenes as young strange.
God no. Laim Neeson is in way to many films and is overused at thus point. Not to mention in my opinion Liam is pretty average to mediocre of an actor. While Phoenix is at least two leagues ahead of him.
I wouldn't say Liam is average but I agree he is somewhat overused and Phoenix would be great.
