Mad Men actor Jon Hamm admits to shedding a tear (or two) while watching Disney's Oscar-winning animation Frozen.

The 43-year-old star, who played advertising executive Don Draper in the popular AMC drama, explained that both Despicable Me 2 and Frozen made him cry.

Speaking to Vanity Fair, Hamm said: The last movie that made me cry was either Despicable Me 2 or Frozen which I watched on the plane coming here. Both of them made me cry because I had to watch a documentary about death gangs in Cambodia called A Act of Killing. I was literally like 'I gotta scrub these out of my brain.'"

When asked which song he preferred, Happy (Despicable Me) or Let It Go (Frozen), he added: "That's a toughy," he said. "That's like gold or platinum." But he did note, "Happy is pretty infectious."
