First, it's interesting to stop and think about why people consider there to be a big difference between studying Shakespeare and looking at musical theatre. As we saw from Katie's presentation, musicals are really prevalent in the popular consciousness, probably especially since what's successful on Broadway often gets made into a movie, which reaches a very broad audience. Shakespeare is well known, of course, but we afford him different status-musicals are, potentially, "just entertainment," but many people think of older plays as something more worthy of serious study. I wonder why we make that "high art" and "popular culture" distinction? Isn't it all culture and part of history? Why is analyzing one kind of script more important than another? Alberto Sandoval Sanchez's book takes a cultural studies approach to the analysis of musicals, which is really another framework for examining a script.
I would encourage people to make room for critiques like this one in your discussions of scripts-be aware that different audiences will experience plays in various ways. But also, be aware that representation carries with it a certain degree of responsibility-how does a play represent a character or group with which the playwright isn't intimately familiar? This doesn't mean that you have to agree with everyone's analysis, nor that playwrights should stick to writing characters in their own identity groups. It's just that it's important not to shut down avenues of inquiry and critique based on identity without giving them some credence. Jose Can You See?: Latinos on and off Broadway uses the first section, entitled "Act One", as a way of critiquing commercial representations of Latino/a characters, and then goes on to examine work by Latino and Latina performers as alternatives to the reigning stereotypes. So, think also of how playwriting itself often serves as an analysis and critique of what came before.
Finally, here's just a little more contextual information with regards to West Side Story, to emphasize that what seems clear to us about how characters come across in that play wasn't always so evident. Broadway in the 1950s was part an parcel of a project that defined what "American" culture and identity were supposed to be. Film and television were big vehicles for that idea of the American dream, bringing it into people's living rooms, and were often exclusionary in their ideas about how people should look in order to participate. Consider these images:


The first is Margarita Cansino, whose father was Spanish and whose career began as a flamenco dancer on the Vaudeville circuit. The second is what happened when she became an "American" film star and sex symbol within the Hollywood system, Rita Hayworth. If one wanted to escape limitations and have a more successful career, serious changes had to be made in a person's image. If Cansino had stayed identifiably Latina, would she have been offered as many substantial "leading lady" roles and become such a legendary figure? So: people writing characters in Broadway plays were shaping the identities of actors and of audience members who emulated those actors. It is the legacy of this environment Alberto Sandoval Sanchez is resisting, some forty years later.
One final suggestion: does the excessive theatricality and "fakeness" of musicals allow us to recognize that these characters and situations are absolutely not real? That is, what about when playwrights work within a style of drama that presents characters as more realistic? Is it more difficult to recognize stereotyping? It's interesting to consider the function of theatricality in scripts in general. This will become a little more clear when we start discussing character in Brecht later in the semester.
