Jon Hamm opens up about his obsession with ‘Dumb and Dumber’

Jon Hamm first obliterated his Don Draper austerity with guest appearances on “30 Rock” and “SNL,” but the “Mad Men” alum plays his zaniest character yet with a voice role in “Minions.” As Herb Overkill, the snazzy British husband of supervillain Scarlet Overkill (voiced by Sandra Bullock), Hamm gets to be rambunctious, silly, and even a little diabolical.

We caught up with Hamm to discuss meeting Bullock, trying new things in film, and the fact that he's seen “Dumb and Dumber” a thousand times.

“Minions” opens in theaters July 10.
