I was reading Interview Magazine's interview with Lee Pace and Jessica Lange, and one part caught my attention:
LANGE: You don’t have to answer this, but how does it feel when there’s a certain discord—and I’m putting it lightly—with an actor opposite you. How do you find your way around that?
PACE: Well, I guess you’ve just got to show up for that first moment, right? You make your entrance, and that’s all I could do, really. I had to love this woman deeply, profoundly, unconditionally, and I did not. But the play does the work, really. Some nights, it hit such beautiful notes. Then there were times when I would look across at her, and I was like, “This isn’t the play we’re doing. You’re angry at someone else right now.” But there’s no redoing it, so yeah.

I can't tell if they're referring to the relationship between Harper and Joe, but the wording makes it sound like there was additional tension between Pace and Gough. Can anyone verify?
