Earlier this year, he revealed what it was like to reunite with the rest of the SATC cast for the reboot table read, saying it was both "weird" and "normal".
"I think the feeling was, 'Oh, my God, this is so weird, right?' " Garson told Page Six.
"And also, 'Oh, my God, this is so completely normal.' So at the same time, this is the weirdest thing ever and this is literally just like, 'Oh, here we are again. Another terrific episode.' "
He paid tribute to the show's fans for keeping it alive after all these years.
"The fans have kept us going all this time, and that's why we do it," he said. "So God bless us for being allowed to do this. And it's because of the fans."
According to Variety, Garson's adopted son Nathen paid tribute on Instagram.
He wrote: "I love you so much papa. Rest In Peace and I'm so glad you got to share all your adventures with me and were able to accomplish so much. I'm so proud of you. I will always love you, but I think it's time for you to go on an adventure of your own.
"You'll always be with me. Love you more than you will ever know and I'm glad you can be at peace now. You always were the toughest and funniest and smartest person I've known. I'm glad you shared your love with me. I'll never forget it or lose it."
It comes amid filming of the long-anticipated series reboot as a trailer was released today.
The new series is executive produced by Michael Patrick King and will not feature one of the four main characters.
Samantha Jones, who was played by Kim Cattrall in the original series and the two SATC films, will not be part of the new story.
