'Mad Men' on 'Inside the Actors Studio': Jon Hamm and January Jones open upAdd to Favorites | Inside the Actors Studio
Creator Matthew Weiner, who was also along for the trip, explains in the clip below why Hamm (who plays the dashing Don Draper) had to audtion six or seven times for the part: "Someone said that he wasn't sexy."
Also, Jones explains the origins of her calendrical first name:
"It is from a book called 'Once Is Not Enough' by Jacqueline Susann," she says. "I think at the end of the book, not to spoil it, but, she trips on acid and gets abducted by aliens after being married and divorced to her father's best friend. It's entertaining... [my parents] just thought it would go good with Jones"
Vincent Kartheiser -- Sterling Cooper Draper Price's straight-laced Pete Campbell -- does a little sharing, too. He talks about his first (and we hope last) experience using a prosthetic penis on a movie set:
"[The director] wanted me to have a fake one so that the actress wouldn't feel offended somehow by a real penis," he says.
Watch the entire show on Monday at 7 p.m. ET on Bravo.
