Sylvester McCoy is a Scottish actor, best known for playing the seventh incarnation of the Doctor in "Doctor Who" from 1987 to 1989, as well as for his role as the wizard Radagast the Brown in "The Hobbit".

He was born Percy James Patrick Kent-Smith in Dunoon, on the Cowal peninsula, to an Irish mother and English father. He was raised primarily in Dunoon where he attended St. Mun's School. He then studied for the priesthood at Blair's College between the ages of 12 and 16, but he gave this up and continued his education at Dunoon Grammar School. After school he moved to London where he worked in the insurance industry for 5 years. He worked in The Roundhouse box office for a time, where he was discovered by Ken Campbell and came to prominence as a member of the experimental theatre troupe "The Ken Campbell Roadshow". Whilst continuing to work in theatre, Sylvester has a few television roles as well as a small role in the 1979 film "Dracula", opposite Laurence Olivier and Donald Pleasence.

Sylvester became the Seventh Doctor after taking over the lead role in "Doctor Who" in 1987 from Colin Baker. He remained on the series until it ended in 1989, ending with Survival. He played the Doctor in the 1993 charity special, "Dimensions in Time", and again in 1996, appearing in the beginning of the "Doctor Who" television movie, starring Paul McGann as the Eighth Doctor.

In his first series, Sylvester, a comedic actor, portrayed the character with a degree of clown-like humour, but script editor Andrew Cartmel soon changed that when fans argued that the character (and plots) were becoming increasingly lightweight. The Seventh Doctor developed into a much darker figure than any of his earlier incarnations, manipulating people like chess pieces and always seeming to be playing a deeper game.  Since 1999 Sylvester has continued acting in the role of the Seventh Doctor in a series of audio plays for Big Finish Productions.

Since his run in "Doctor Who", Sylvester has continued to work extensively in film, theatre and television, and in 2011 began filming for "The Hobbit", a three-part adaptation of the book, where he portrayed the wizard Radagast, alongside fellow "King Lear" actor, Ian McKellen.
