Passage: Between 2004 and 2012 he starred as an acerbic physician specialising in diagnostic medicine, Dr. Gregory House in the Fox medical drama House. For his portrayal, Laurie assumed an American accent. Laurie was in Namibia filming Flight of the Phoenix and recorded the audition tape for the show in the bathroom of the hotel, the only place he could get enough light. While working on Flight of the Phoenix, Jacob Vargas operated the camera to shoot Laurie's audition tape for House. Laurie's American accent was so convincing that executive producer Bryan Singer, who was unaware at the time that Laurie was British, pointed to him as an example of just the kind of compelling American actor he had been looking for. Laurie also adopted the accent between takes on the set of House, as well as during script read-throughs, although he used his native accent when directing the House episode "Lockdown". Laurie also served as director for the episode "The C-Word" of the show's final season.Laurie was nominated for an Emmy Award for his role in House in 2005. Although he did not win, he did receive a Golden Globe in both 2006 and 2007 for his work on the series and the Screen Actors Guild award in 2007 and 2009. Laurie was also awarded a large increase in salary, from what was rumoured to be a mid-range five-figure sum to $350,000 per episode. Laurie was not nominated for the 2006 Emmys, apparently to the outrage of Fox executives, but he still appeared in a scripted, pre-taped intro, where he parodied his House character by rapidly diagnosing host Conan O'Brien and then proceeded to grope him as the latter asked him for help to get to the Emmys on time. He would later go on to speak in French while presenting an Emmy with Dame Helen Mirren, and has since been nominated in 2007, 2008, 2009, 2010, and 2011.
