Mad Men 'all change' for fifth season

The fifth season of Mad Men is all about change and trying to "get back to normal", says the series creator Matthew Weiner.

January Jones told reporters that she feels like her role, Betty, is a different character each season.

Weiner said the script, although set in the 1960s, has relevance with what is happening in the world today.

He said: "The world is actually in the midst of a tremendous change. And we kind of try to present that in its gradual state in the show."
