"Sebastian and Anthony have a very different energy, but they are a perfect couple. They now look to me like they're a married couple" Daniel Bruhl said this about working with them in some official tfatws book. Thought it might interest you.
Me wanting all the tea on the official tfaws book blessing the stackie status:
I'm here for all of that. If you find, link me up. I feel happy when people see what I see.
If nothing more I think Anthony and Sebastian are at least work husbands. I've seen Marvel bromances. Like the one between Chris Evans and Chris Hemsworth where Hemsworth in one article was ready to adopt Evans into the Hemsworth brood and Evans didn't object. Or Tom Hiddleston and Chris Hemsworth. Or RDJ and Chris Evans with RDJ blessing the Stony fans...But nothing tops Stackie for me. They literally got a show because of their mad chemistry. The way they feed off each other's energy and want to be close. The way they bless and support each other's projects and want to do stuff outside the project together. They have their inside jokes and running gags only true stackie fans get.
I just enjoy their interactions so much and can't wait until their next project together and next promo tour. Hopefully they will be in touching distance soon because I am going through stackir withdrawals.
