Yes. There is *more often than not* an undeniable chemistry with the scene partners, and nuance to the performance, that is achieved through weeks of rehearsing from page to stage with the other actors under the direction of the director... which is often impossible to have otherwise. It doesn't mean the performance won't be worthwhile or thrilling or possibly bring its own nuance and chemistry... but that is a less common result of alchemy.
This is just part of the reality of the understudy and the process of putting them into the role they're covering rather than what they were cast to play normally and rehearsed for. |
