Still, much of the dialogue is taken directly from the book. Many of the cultural references have been left in as well, such as English currency. The modern influence is found in the setting rather than the dialogue. For example, instead of lighting a candle in one scene, Scrooge flips on the lights and turns the heat up. In another scene, where pawnbrokers are selling Scrooge's belongings after his death, they are dressed like modern garbage men.
Scrooge even uses a computer in one scene.
There have been countless versions of the play, and he was able to use what he liked from other adaptations. Mostly, though, the play comes directly from the novel. There are no real surprises in his adaptation, the play being such a timeless and well-known story. David Bradley plays the part of Marley, whose ghost appears to Scrooge early on in the story, and Josh Grotte plays Bob Cratchett. Scrooge is a very familiar character, and Rose feels confident in his depiction.
