Chapel and Korby couple

Cillian O’Sullivan: Jess Bush is such an amazing actor. I think she’d have chemistry with a stone if she wanted to. We did the chemistry read for the auditions, and Jess, in the chemistry read, really gave. She was very generous in that audition. I’ve been in chemistry reads before, where, you know… And on Zoom, it was on Zoom, too. So, that’s a difficult thing to accomplish on Zoom is a chemistry read. Like, it’s one thing for an audition, but she just gave me everything that she could in that room. And that was a huge part of getting the role, was the chemistry that we had to get her in that Zoom room. And that was as much of a part of Jess’ effort as it was mine.

In his exclusive interview withScreenRant,Cillian O’Sullivan credited the writing by Kirsten Beyer and David Reed for making Dr. Roger Korby likable, at least to audiences, as well as Chapel’s USS Enterprise crewmates (except for Spock).The other person in “Wedding Bell Blues” who loathed Korby on sight was Trelane(Rhys Darby), who warped reality to marry Chapel to Spock instead of Roger.
