"John Simm was born in Leeds, Yorkshire. His father, Ronald, was a local musician who taught him to play guitar. John would join his father on stage in the working men’s clubs playing the guitar, he made his debut singing Elvis’s Wooden Heart, and they called themselves Us2.
   In 1986 and at the age of 16, John went to Blackpool Drama College and enjoyed three years of drinking and starring in West Side Story. He then attended the Drama Centre in London at the age of 18, where he studied the Stanislavski School of method acting. Coming from a working/lower middle class upbringing to suddenly being surrounded by those from more privileged backgrounds, he educated himself by reading classic plays and novels."

   Named after Doctor Who's Rose Tyler, Sam was destined to become a time traveller. Or is that the case? Did his 2006 accident leave him with a broken sense of reality or did he infact jump timelines? It becomes the pursuit of Sam Tyler to find out even as he clashes with nearly everyone around him, especially his boss, DCI Gene Hunt.
   When the two aren't trying to knock each other around, Hunt and Tyler work together, bringing 2 entirely different views to each case. Even though Sam's knowledge of the future and multi tasking often clash with Gene's odd sense of humanity and gut instincts, they end up feeding off of and learning from one another.
   Though he seems to make his place in the station in 1973, Sam still exists in two different worlds as he often hears the noises of his room in St. James hospital in 2006. He is also spoken to by Neil, a late night lecturer on the telly, and the girl in the Test Card, who all speak to Tyler as if they know of his predicament. Even though he responds to them, he still finds himself unable to wake up, only futhering his goal to find that "definitive step" to get him out.
