Well, thanks mostly to a recent viewing of Frosty the Snowman and its much-maligned stepbrother Frosty Returns, I decided it would be awfully fun to glance over the histories of our favorite AMC ad execs and their colleagues and see what early glimmers popped up that some fans may not be privy to.
Our very own Peggy Olson (Elisabeth Moss), the inspiration for this post, believe it or not voiced the little budding magician Holly to John Goodman's new-era Frosty in 1992's Frost Returns.
Though he only had one line, Mr. Don Draper himself (Jon Hamm) encountered his debut performance in a one-line role in the geriatric astronaut romp starring Clint Eastwood and Tommy Lee Jones, Space Cowboys, in 2000.
Our favorite self-involved, self-destructive firm partner Roger Sterling (John Slattery) had an early regular role in the 1988 television series version of the 1967 classic film The Dirty Dozen.
Mommy dearest herself, Betty Draper (January Jones), had some parts in teen comedies, but one of her first on-screen roles was as a student extra in the little-seen thriller The Glass House in 2001.
We all know Pete Campbell (Vincent Kartheiser) as the pompous little snob who's too big for his britches, but he actually had a few jobs as a child actor, one in the literary adaptation The Indian in the Cupboard (1995).
The curvaceous Joan Holloway's (Christina Hendricks) sex appeal didn't start in the hallways of Sterling Cooper; she had a stint on MTV's late-night teen sex soap Undressed in the late-1990s.
Before he was the gruff older partner Bert Cooper (Robert Morse), he originated the 1961 starring role on Broadway and headlined the film adaptation of How to Succeed in Business Without Really Trying.
Before she was Megan (Jessica Pare), the hot new secretary on the block, she starred in the cheeky school-girl teen movie Lost and Delirious in 2001, alongside Piper Perabo and Mischa Barton.
