One of the things which happens when rehearsals start is staff and cast start calling cast by their character names. I have been in shows where I did not know many of the cast's IRL names, I just knew them as the characters they played.
This show, the staff is calling us by our IRL names, which is confusing because (a) I don't know their IRL names and (b) sometimes we have duplicates (two Gregs) and sometimes IRL names of one person is close or the same as the character name of another. We have an Evelyn (American pronunciation) and a character named Evelyn (Britt excruciation). There is a Reina IRL and a Reno in the play. And so on.
