David Cann is a British actor who has had many roles in theatre and television.

He graduated from RADA in 1973 and spent many years working in theatre, including various Shakespeare plays before eventually branching out into television, including roles in the BBC children's drama Grange Hill. When he married he cut down his work schedule to become a househusband after his son was born in 1989 whilst his wife worked full-time as a doctor. His wife died of breast cancer in 2001.

David Cann is probably familiar with many people due to his roles in various works by Chris Morris. Cann played various roles in Brass Eye, a spoof current affairs show aired in 1997, and many roles in the disturbing sketch show Jam.

Cann is possibly best known for his character "The Doctor" from Jam, a recurring role in the series. "The Doctor" is a seemingly "normal" physician working in a standard British medical practice. However, he has a habit of treating his patients in bizarre and often disturbing ways, such as prescribing a young girl heroin, making a man with a headache jump up and down in order to make his penis swing (while mirroring the patient's bewildered jumping himself), blinding himself with an intense light in order to avoid awkward questions and insisting on examining a patient by telephone, even though he is in the same room.

In 2003, Cann played another doctor in the popular British soap opera EastEnders. The irony of this piece of casting was not lost on the many fans of Jam. This scene has been edited to use the style of Jam. 4Q" target="_blank">http://www.youtube.com/watch?v=MTH841rt_4Q
