This ought to be superbly easy!
There was a point of time in his life when he wore two watches on the same hand, so that he could keep track of time in his own country and in Switzerland too, where his children studied. He even confessed in a recent interview that he has worn three watches on the same hand at a certain point of time in life, but that was simply because he thought it looked stylish.
Now, years later, he has worn two watches on the same hand for a film that itself is a cheeky nod towards his younger days.
Who is this person, and which film are we talking about?
Happy quizzing, and have a nice life, folks!
