Dolores Costello, ‘20s star and Drew Barrymore’s grandmother, should be remembered for this reason: author

Drew Barrymore came across photos of her late grandmother on Instagram, sparking interest in "The Goddess of the Silent Screen."

Terry Schulman, an acclaimed writer who chronicled Costello’s story in his book "Film’s First Family: The Untold Story of the Costellos," told Fox News Digital there are plenty of reasons why film buffs should learn about the star’s life and legacy today.

"Known in the 1920s as ‘Goddess of the Silver Screen,’ Dolores Costello was one-third of the first great family of movie stars," he said. "Her father, Maurice Costello, was the first screen heartthrob, her sister Helene starred in the first all-talking picture."
