Five years ago, James Purefoy was attached to a new TV version which fell through, and then attached again to star in a TV movie/backdoor pilot last year... which also fell through. In the interim, we also heard Dougray Scott's name mentioned. But hopefully this Adam Rayner version will actually happen. It sounds closer to being a reality than any of the prevoius versions! According to Deadline, Simon West (The Expendables 2) will direct the Rayner pilot... and it's set to start shooting later this month! Alias writer/producer Jesse Alexander wrote the script and executive produces; Brad Krevoy produces. Roger Moore was involved in a producing capacity in previous revival attempts, but there's no word now on whether or not he's involved in this version. (It would seem like a possibility, however, since he previously worked with Krevoy on A Princess For Christmas and Boat Trip.) There is no U.S. network involved yet, but the plan is to shop the completed pilot.
The Saint is not a spy, but he's had plenty of espionage experience nonetheless in his history in print and on screen. It sounds like this version of The Saint will play up the espionage angle. According to the synopsis reported by the trade blog, "A master of disguise, improvisation, martial arts, firearms and espionage and the quintessential English gentleman, [Templar] is hired by certain government agencies for special assignments."
This isn't the only Saint production in the works. In January, RKO announced plans to remake one of their Saint features... but supposedly their rights preclude them from altering any of the 30s or 40s dialogue, and restrict them to the brief running time of the originals, so I'm not sure how far they'll get with that.
