I know the person tweeting about this. He didn't see the screening of JOY, a friend did. That person isn't necessarily an awards aficionado or a tastemaker.
Every single Twitter reaction is hype based on one screening reaction, so let's not get too excited.
What we can take from this is that there could be an actor campaigned in all four categories again and if DOR and his actors campaign like they did last time it is possible to see 4 acting nods for this.
And "Edgar Ramirez is happening" means he can foresee this kick starting his career, not that he'll be Oscar Winner Edgar Ramirez.
