I found out a pretty good article about acting for MT actors, saying that acting has been taken as the extra - the least important - of the 3 main core MT disciplines. "Many musical theatre students get only a ‘smattering’ in acting – a general short course in the basics".
Even an actress says that she regrets not having enough acting courses at college.
After reading this article I can relate it to a lot of US Colleges programs with enphasis in acting, dancing, singing. Carnegie Mellon has an emphasis in acting, for example, they even do not have a dancing audition, and their students do great not being necessarily great dancers.
So far I ask myself how important are these acting techniques for MT actors such as Stanivlasky, Meisner, Hagen, Suzuki, Viewpoints because even after college these techniques improve the acting skills of an actor.
After studing these 3 disciplines I can say that it all depends on what you want and the career path that you want to take.
