This series regularly gets repeated on UK TV, the ITV3 or ITV4 channels. Only 12 done by Gambon, with 2 different Madame Maigrets, as the two sets of 6 were done a couple of years apart, the later set found the actress unavailable, which was a stroke of luck as they asked the delicious Barbara Flynn to become his wife, adding a cheeky irreverence to the usually subservient, if long-suffering wife.
I must correct the usually pretty accurate Prismark, whose review says "threw money into this production, just like the BBC had 30 years earlier" (the Rupert Davies version). This is palpable nonsense, as though the BBC ones were a cult hit back then, those shows were clearly done on the extreme cheap, shaky sets like Crossroads, and some actors (especially in the early ones) who could barely avoid bumping into the furniture!
This version was expertly done, Budapest subbing for Paris, a good set of actors for Maigret's team, and some good writers and directors. Prismark is also wrong, the shows were not all 2 hours long, this one WAS, but the rest came in at about an hour and 20 minutes, which is about right (longer than the the Davies ones, but nothing like as long as the Atkinson shows, which had lots of padding and dragged on for 2 hours!).
