Dark Shadows

After completing Paramount's Tarzan and the Great River opposite Mike Henry and Jan Murray that was shot in Brazil,^[9][10] executive producer Dan Curtis offered her the contract role of "Laura Collins" on his ABC-TV daytime series, the cult classic Dark Shadows in November 1966.^[11] She went on to appear in sixty-two episodes,^[12] and became the show's first supernatural character, playing an immortal phoenix-woman who is burned in a fire and reborn to spend another century on Earth. After her present day incarnation was again consumed in a fire, she returned during the flashback story which took place in the 19th century, as yet another reincarnation of "Laura Collins". She appeared in a feature film inspired by the series, MGM's 1971 Night of Dark Shadows opposite David Selby.^[10][13]

In 1970, Millay was offered a daytime role as "Kitty Styles" on the CBS soap The Secret Storm. Her run on this show gave her the opportunity to work once again with former Dark Shadows alumni Robert Costello, who was a producer on both shows, and Joel Crothers who played "Joe Haskell" on Dark Shadows and "Ken Stevens" on The Secret Storm.
