Now I'm sure that I'm not on my own on this one so I would like to see a bit of feedback as it helps me distinguish between those who know what's what and those who Google.
So I'll get the ball rolling, there is a Mews house in London and its second floor flat has been in:
The Saint, The Baron, The SAS film, Minder, Lovejoy, Purfumo, Man in a Suitcase and it may have been in MC Vicar and the Champions have deffo been in it!
There is also a house on the corner of a London street and it has about 5 steps going up to the front door.
It's been on Minder, The Sweeney, The Professionals and I think the SAS film. I can't be sure.
I think Euston Films own this property and use it to house the cast of the 'Double Deckers' as it was Lou Grades dying wish they be brought up as a family, I think 'Tiger' became a heroin addict.
So come on get your anoraks on and leave your Google box empty, if you know this house and have any other films or shows you have seen it in, then come clean.
I would also be interested in other backdrops that people have got onto as I do like to think back and say "oh yeah I forgot about that"
