Which production company made BBC’s Sherlock alongside the BBC?

Hartswood Films made BBC’s Sherlock alongside the BBC.

Hartswood Films is the production company founded by television producer Sue Vertue. It produced Sherlock with the BBC, bringing together the creative team led by Steven Moffat, Mark Gatiss and producer Sue Vertue. The company is also associated with other British television productions, including Coupling and Dracula.

Sherlock’s production model helped the programme stand out from ordinary weekly detective dramas. Its episodes were feature-length, heavily scripted productions filmed in locations including London and Cardiff, while the stories updated Doyle’s nineteenth-century detective for the age of smartphones, blogs and online news.

The company is sometimes confused with the BBC itself or with international distributors and broadcasters. The BBC commissioned and transmitted the series, but Hartswood Films was the named independent production company behind the programme.
