United Kingdom, Feb. 26 -- Macaulay Culkin and Brenda Song use Home Alone to teach their children about stranger danger.

The couple recently showed Dakota, four, and Carson, three, Macaulay's 1990 Christmas classic, so they can improve their safety skills.

Brenda, 37, told E! News: "They love all the hijinks and the traps and stuff. They have no real concept [of the danger]. My oldest gets it more than my younger son.

"I remember at the end going, 'See, your mama's here right next to you. Don't you want to give me a hug?' I didn't leave. I'm so terrible, but I feel like your children have to be a little scared. Fear goes a long way."
