Guest star.

"All My Children" fans may know Ronald Guttman best as Zach Slater's (Thorsten Kaye) murderous father Alexander Cambias, but last night he played a father of a different sort on "Mad Men." Guttman appeared in the April 29 episode titled "At the Codfish Ball" as Don Draper's (Jon Hamm) father-in-law.

In the episode, Megan Draper's (Jessica Pare) French Canadian parents paid the newlyweds a visit (her mother was played by Julia Ormond, "Temple Grandin") and it was evident from the start her father Emile disapproved of her choice in husbands. He expressed later in the episode his disapproval over Megan giving up on her dreams in exchange for all the trappings that go along with being Mrs. Don Draper.

In addition to being on "Mad Men," Guttman has also been seen in the series "Royal Pains," "Blue Bloods," "Gossip Girl" and "Cold Blood." He was also in the HBO mini-series "Mildred Pierce."
