According to Stephen Fry, he and Hugh Laurie were initially very hesitant to take part in this movie, as they could only imagine the response that the critics would have towards such a meta-casting of Laurie, Fry, and Dame Emma Thompson "playing" old college friends. It was producer and director Sir Kenneth Branagh who waved away such concerns and encouraged them to take part.
