He is now familiar to Mad Men viewers as the flawed but always dapper advertising genius Don Draper.
But Jon Hamm has not always enjoyed such challenging roles in his career.
In a new Vanity Fair profile, the 43-year-old actor has described his previous job of working on soft porn movies as "soul crushing".
The Mad Men actor was a set-dresser on softcore adult movies in the late 1990s and says it was one of the worst jobs he'd ever had.
Discussing a recently resurfaced episode of The Big Date which he appeared on in 1996, he said: "I was actually at that time working as a set dresser for Cinemax soft-core-porn movies. It was soul-crushing."
