Behind-the-scenes information

Jayne Mansfield (born April 19, 1933) was briefly married to Biff Tannen in 1970 of the alternate timeline where an elderly Biff used the DeLorean time machine and the Grays Sports Almanac to make his younger self a millionaire, following his divorce from Marilyn Monroe in 1960.


At some point in the 1960s, Jayne Mansfield had retired from acting and started dating Biff Tannen. Biff's first marriage had ended on account of his failure to make Tannen Pictures profitable, revealing his wife wanted more out of life than he could provide. Jayne Tannen moved to Hill Valley after they were married. It was unknown if she was involved in BiffCo or had engaged in any worthy activities. She did, however, seem to have an apparenly charmed life living in Tannen Manor, which was a testament to her husband's prosperity. The mansion, ironically, would indirectly doom their marriage. In 1972, Jayne had discovered a fallout shelter beneath the mansion. She was perplexed why this room contained pictures and dossiers of Lorraine Baines McFly. Jayne soon correctly deduced that Biff did not build this out of concern for civil defense, but a secret room to nurture his obsession with another woman. Jayne promptly filed for divorce.

The following year, Biff secretly murdered Lorraine's husband, George McFly, then married Lorraine with the promise that he'd financially help her family. At the wedding, he proclaimed to the press "Third time's the charm!"

Behind the scenes[]

  • Jayne Mansfield and Marilyn Monroe aren't named in the comic books, but Biff's wives bear their likenesses, and the footage in the Biff Tannen Museum video in Back to the Future Part II further show their identities through actual photographs of the actresses altered to include Tom Wilson as Biff.
    • The photograph of Biff and Jayne was originally of Jayne Mansfield and her then boyfriend Nelson Sardelli in Dallas, Texas in May 1963.[1]
  • In reality, Jayne Mansfield died in a car accident on June 29, 1967. This means, ironically, that being married to Biff saved her life in this ABC timeline.
