The man is an absolute superstar.

Kate de Ban was in Heathrow Airport on Thursday morning when she spotted a familiar face in a W.H. Smith bookshop. It was, of course, Bryan Cranston himself, who had been in the UK promoting his autobiography 'A Life In Parts.' She takes up the story... 'So I saw a man in the front of a book in WH Smiths. A bit hunched over, leaning on a table display, he looked kind of familiar but under a baseball cap... and I thought, that's cool, someone has obviously recognised him and he's signing a book for them. 'But then I watched as he went over to the wall of books and I couldn't see what happened next, there were more displays in the way. When he got back up and turned he caught my eye and smiled. So after he left I went over to see what was what and found this... 'Talk about cool. Right time and right place for a proper treat. Thank you Bryan Cranston for making my day.' This is the message he had left on the inside cover of the book he was signing... 'Thank you for checking out my book. I bought this copy for you, seriously. It's yours for free. Keep the receipt. Hope you enjoy the book and have a nice day, Bryan Cranston. 'October 27 2016, 11.50am. Heathrow Airport. U.K.' https://twitter.com/FilmFan1971/status/791716384300535808
