The Tinker Tailor Soldier Spy star almost contacted police after he discovered his everyday movements were being written about on the microblogging site, but he managed to resolve the issue with the mystery perpetrator.
He tells the Daily Telegraph newspaper: "I would say that it was the strangest fan experience that I've ever had. I had someone live tweeting my movements while I was in my own house.
"It was such a strange and a direct thing to see these tweets saying what I was doing as I was doing them. I found it really worrying, and, yes, of course, very hard to deal with. I worked out after a while who it was who was doing it so, when it came to it, I didn't actually call in the police, but I was prepared to do so.
"I'm not going to say any more about it. The person concerned knows now what I felt about it. I just found it very hard to come to terms with the idea that an individual could look into my house like this, and talk about me online, and think it is a perfectly okay thing to do."
