Before Jon Hamm was a working actor, he worked as a set dresser on Skinamax movies. So, you would think that the second the producers saw him bend down and clean the tables of butt prints, they would offer him an on-camera job. But, he told Howard Stern they didn’t ask him.
I betcha the producers on all of the softcore porn movies he worked on regret not hiring him. But then again, they would not be able to show his Hammaconda, so it is not as bad as a decision had been hardcore porn.
