Broadway's buzziest comedy is getting the full tabloid treatment, and Rose Byrne and Kelli O'Hara aren't holding back.

The stars behind Fallen Angels discussed what makes audiences laugh night after night in a candid Tony Watch Q&A with Deadline. They revealed the mechanics behind their comedic timing and the props that keep the laughs rolling. Not everything on stage is what it seems—especially the cocktails.

Byrne and O'Hara's partnership has become central to the show's success. In the interview, they get candid about the craft, the chaos, and the moments that had even the stars cracking up mid-show.

As the Tony Awards approach, Fallen Angels remains the season's most talked-about comedy.
