The Guardian has an article titled "Jim Broadbent, Matthew Macfadyen, Sam Claflin: three actors, one man" which interviews the three actors on their role in Any Human Heart.
Among the many comments, Matthew had this to say:
While filming an adaptation of Anthony Trollope's The Way We Live Now in 2001, Macfadyen abandoned his research-read of the novel. "My character was described by Trollope in totally different terms, a totally different person to me. You have to remember it's not the book, ultimately, that you're shooting, but rather the scripted adaptation. As an actor you can't play the book, only the moments – very simple moments – in the script. I've never enjoyed watching something as much as I've enjoyed reading it."
Sunday Mercury also has an article discussing the star-studded epic.
If Matthew could have lived in another era, he says: “I would probably go back to an age when celebrity culture wasn’t quite so on the pond life level. And I do like the suits they wore in the 1930s and 40s.”
