''To make a good extra you have to be good at blending into the background, not making big movements and having the ability to mime rubbish with no one knowing.''

An actor has been an extra in 200 shows.

John Walker has made 2,000 appearances in the background of several hit British shows including 'Coronation Street' and 'Doctor Who', and even met his future wife Neilum - also an extra - on the set of medical drama 'Doctors'.

He is quoted by the Daily Mirror newspaper as saying: ''To make a good extra you have to be good at blending into the background, not making big movements and having the ability to mime rubbish with no one knowing.''

John has appeared alongside a number of big stars during his time on the small screen such as 'Only Fools and Horses' star Sir David Jason, 'Harry Potter' actor Daniel Radcliffe and 'Billy Elliot' actress Julie Walters.
