The cast on Broadway has come from a production in Los Angeles, staged at the same time Philadelphia’s Arden Theatre Company was running its own. The Arden’s version, directed by Ed Sobel, came off a bit differently than the Broadway production, which opened Thursday night. The second act — when Norris really lets loose with his characters’ intimations about racial issues surrounding the sale of a property to a white couple in a solid and upscale African American neighborhood — is mined more for laughs on Broadway, where it’s directed by Pam MacKinnon. The Arden’s production, while undeniably funny, was more intense as it progressed, giving the issues at stake a higher focus. While that’s the interpretation I prefer, there’s nothing awry about the show on Broadway, where it provides all the food for thought and lets you do the grazing by yourself.
