You have questions. I have some answers.
Q: There are so many interesting and hilarious characters in television series and I'm wondering how much of it is the actor's interpretation of what the script writers came up with. Or are they given a basic blueprint and then let loose with it. I'm thinking of characters such as Klinger on “M.A.S.H."
A: It depends on the show, the actors and who’s in charge. “Curb Your Enthusiasm,” for example, reportedly allows a lot of improvisation. And anyone working with Robin Williams in his comedic prime knew how he could take off in a scene. Jamie Farr, who played Klinger, brought some of himself to the role (such as both being from Toledo, Ohio). But that was also a case where the writers were so good, why not trust whatever they come up with? To be sure, some actors are in charge of their characters (Roseanne Barr is one who comes to mind). At the same time, there are writers who are as much or more influential. One actor told me about a writer so unbending that his lines had to be said exactly as written – including every “uh” and “ooh" on the page.
