Those who can, do. Those who cannot, don't perform. not everyone is able to do Broadway, and have the discipline to take care of themselves so they can do eight shows a week. Performing on Broadway is like the life of a professional athlete you are either dedicated and have the strength to do it, or you don't. If athletes don't perform well or at all, the team loses - see what happened to Comet? The team lost and they want to blame the owners or in that case, the producers. Why ill-prepped performers or delusional people in many cases, are surprised at the strength and stamina it takes to do a show 8 times a week for 2 to three hours a show with the requirement of doing two shows on two days a week is beyond comprehension. Professional theater is the place that tests the metal of a persons natural born talent and their dedication to be a performing artist. Go home if you cannot do what is required of the part and expected by the audience, just stop lowering the expected standards established by great playwrights and composers and actors just because someone might be required to be on the stage almost the entire length of the play or musical they are performing in. I mean, can you imagine, "I have to sing for the entire time? " "You mean I am required to memorize all these lines and say them over and over 8 times a week?" "I'm sorry my ability to sing can only carry me for six shows so you'll just have to have another actor fill in, but pay me the same and give me an award, or I can only do six shows of a play because, my talent to be convincing in a part can only be conjured up for seven shows. I want to be on Broadway but you must accommodate my limitations." Next!
