We're celebrating the tenth anniversary of Matthew Coniam’s “The Annotated Marx Brothers: A Filmgoer's Guide to In-Jokes, Obscure References and Sly Details”. In this retrospective, we explore how the book came to be—and how it ultimately became something quite different from what the title might lead you to expect.

What sets it apart from other books on the Marxes? Is an updated edition on the horizon? And does Matthew still hate “Duck Soup”? These and other pressing questions will be lightly dodged before we inevitably try to sell you a copy.
