Jon Hamm and Daniel Radcliffe keep in touch via iPhone app 'Words With Friends'.
Actor Jon Hamm reveals he plays against Radcliffe on the word-building game - which is similar to Scrabble - as a way of staying close after they appeared in TV mini-series 'A Young Doctor's Notebook'.
Hamm says: "We do. We were playing 'Words With Friends' together for a while. Because that's basically the 21st century way of staying in touch."
Jon says he is fan of the "talented" 24-year-old actor Daniel Radcliffe and says: "I'm a fan of his. He's a lovely guy. He's wildly intelligent and super funny and super talented.
Chatting to 'E' Hamm adds - "I like to have people in my life who are all three of these things."
It was recently revealed Jon was going to have throat surgery to remove a single polyp - a growth of abnormal tissue - after his representative confirmed he was going under the knife.
He was overheard discussing the procedure - which his rep said is routine - with his on-screen ex-wife January Jones at an Emmy Awards after party last week.
