After leaving "The Secret Life of Us" in 2004, Johnson went on to star in the dark, black comedy "The Illustrated Family Doctor" as Gary Kelp, a man condensing The Illustrated Family Doctor medical guide. Unfulfilled in every way, Gary starts to develop the physical symptoms of the ills he is transcribing and his life begins to really fall apart. The film divided viewers and critics, with the film resulting in a love-it-or-hate-it divide and was nominated for a handful of awards including Best Adapted Screenplay at the 2005 AFI Awards.
