was planned to be broadcast in mid- to late 2009. The intention was to produce a full series should the pilot prove to be successful. However, the first version of the pilot – reported to have cost £800,000 – led to rumours within the BBC and wider media that Sherlock was a potential disaster. The BBC decided not to transmit the pilot, requesting a reshoot and a total of three 90-minute episodes. The newly shot episode, says journalist Mark Lawson, was "substantially expanded and rewritten, and completely reimagined in look, pace and sound". The first series of Sherlock was produced in reverse order; "A Study in Pink" was the last of the three to be produced. This was because episode writer and co-creator Steven Moffat was busy with the fifth series of Doctor Who. Background information on Sherlock and Mycroft's relationship was cut out of the final episode as it was viewed as giving too much away. For the pilot, the roles of Sally Donovan and Angelo were portrayed by Zawe Ashton and Joseph Long respectively but were portrayed by Vinette Robinson and Stanley Townsend in the hour-and-a-half episode.

The change from a pipe to a nicotine patch reflected changing social attitudes and broadcasting regulations. Director Paul McGuigan says that using modern technology is in keeping with Conan Doyle's character, pointing out that "In the books he would use any device possible and he was always in the lab doing experiments. It's just a modern-day version of it. He will use the tools that are available to him today in order to find things out". Sherlock Holmes still lives at the same Baker Street address as in Conan Doyle's stories. However, it was filmed at 185 North Gower Street.

It was written by Moffat and directed by Coky Giedroyc. A seven-hour night shoot took place on 20/21 January at the No Sign bar in Wind Street, Swansea. The bar had been redesigned as an Italian restaurant for the shoot, where Holmes and
