Jon Hamm admits delving into darkness of his character Don Draper was 'challenging'

Jon Hamm, who plays the troubled Don Draper on the hit AMC drama 'Mad Men,' has opened up about his role.

The 44-year-old actor admitted that delving into the darkness of his character Don Draper was "challenging" at times, People Magazine reported.

Hamm, who recently revealed he a stint in rehab last month for alcohol addiction, said that it's not easy to maintain that head space for a long time, adding that people want to go home and want to wash it off and leave it at work.

Hamm said he has been fairly capable of saying goodbye to Don, but he still holds on to aspirations for the character he played for seven seasons.

He noted that his hope for Don is always that this incredibly talented, yet incredibly troubled man would find balance in his life, would find peace in his life and hopefully, he does.
