Heh, what is it about this scene that prompts this kind of ask?
I do very much appreciate their chemistry and the intensity and believability Danielle Savre brings to the role, but I don’t think I’ve personally noticed what you’re talking about when it comes to actresses visibly not into it. So many different factors are at play, what kind of show it is and who it’s targeted at, what stage the relationship’s at, what life stage the character’s at, and then if there’s certain attention being paid to not come across as male gazey or salacious or just network pressure to tone things down and so on.
Yeah, of course there are actors who might be stiffer and awkward with female costars while offering a much smoother, more enthusiastic point of comparison with male characters but I don’t really notice it much, or look for it, I guess. It requires so much reading into motivation, I’m usually like, oh, there must’ve been a reason, and shrugging.
