Mallory was the second-oldest child of Elyse and Steven Keaton, behind braniac older brother Alex P. Keaton, portrayed by Michael J. Fox.
Born in 1966, Justine is three years older than younger brother Jason, who was also appeared on the small screen in the 1980s in sitcoms like Silver Spoons (1982-84) and It’s Your Move (1984-85).
During their sitcom heyday, Justine and Jason Bateman appeared in two TV movies together.
After their 80s splashes, both siblings continued a fairly steady stream of television and movie appearances into the 2000s. But, while Jason has ramped up his silver screen appearances in the 2010s and 2020s, Justine’s on-screen roles have become more spaced out.
Today, Justine Bateman continues to write and direct, including for her directorial film debut Violet in 2021.
