"March 19th,1979. And we were never the same again," Beckinsale, 47, wrote in a post shared to Instagram. Thank you to everyone who has kept him alive in our hearts and on our lips. And love to everyone missing a shining, special person of their own. I wish I was with my mum today xxx."

Beckinsale, who was just 5 years old at the time, also included a newspaper clipping with her father’s obituary. The headline reads, "TRAGEDY."

"It’s so weird as a five-year-old to look out in the street and see people reading the paper and crying while you’re crying and your mum is crying and your granny’s crying," the "Serendipity" star said. "Even though it was the worst loss that I have experienced I was able to share it with people who genuinely, even if they didn’t know him, really seemed to love him."
