For our money, much of the show's success is down to star Jonny Lee Miller, who makes for a fantastically frenetic Holmes. So this week's Friday Fiver is a celebration of the men who came before Miller - the five greatest actors to bring Conan Doyle's detective to life on the small screen...

Jeremy Brett - Sherlock Holmes (1984-1994)
Often named as the greatest on-screen Holmes in any medium, Brett made for a wonderfully neurotic, fiercely intellectual Sherlock, paired first with David Burke and later Edward Hardwicke as Watson. Though Brett's ill health is evident in some of his later performances - the actor passed away in 1995, a year after the final Sherlock Holmes series aired on ITV - his portrayal is still fondly remembered by fans.
Peter Cushing - Sherlock Holmes (1968)
Having already played Holmes in Hammer's iconic 1959 film adaptation of The Hound of the Baskervilles, Peter Cushing - one of the greatest actors the UK has ever produced - reprised the role in 16 episodes of the BBC's '60s adaptation, taking over from original star Douglas Wilmer. Cushing would later claim that a hectic production schedule had negatively impacted on his performance, but in our opinion, he remains a great small-screen Sherlock.
Benedict Cumberbatch - Sherlock (2010-present)
Of course, a list of the greatest small-screen Sherlocks would not be complete without Mr. Cumberbatch, who did a marvellous job of reinventing Conan Doyle's 'tec for a modern age. This new Sherlock is often cold and aloof, but there's something dashing and romantic about him too - just ask a certain section of Sherlock fandom, who've filled the internet with their own... imaginative fiction.
Tom Baker - The Hound of the Baskervilles (1982)
Shortly after completing his seven-year tenure on Doctor Who, booming-voiced Baker took on another famous fictional role. This BBC adaptation of Hound is not well-loved by most critics and Baker doesn't really fit Conan Doyle's depiction of Holmes. But we'd watch the cult legend in pretty much anything - he brings a charm and humour to any role he plays.
Basil Rathbone - Suspense, 'The Adventure of the Black Baronet' (1953)
Alright, so this last one is cheating slightly; Rathbone is best known for playing Holmes on the big-screen and this Suspense episode - intended as a pilot for a series that never materialised - was the only time he portrayed the character for television. But we just *had* to include old Basil in our list - he made Sherlock an action hero decades before Robert Downey Jr attempted the same...
