Steer clear of Melissa McCarthy when Planes, Trains and Automobiles is on – the funnylady says her love of the 1987 movie might make bystanders uncomfortable.
Playing a rapid-fire Q&A session known as the Cagle Exercise, McCarthy reveals to PEOPLE and Entertainment Weekly editorial director Jess Cagle during their latest sit-down that the dramedy – which stars Steve Martin and John Candy – is the movie that always makes her laugh.
“It’s my favorite movie,” the 45-year-old says. “I can’t watch it in public because I laugh so hard, and then I cry so hard that people are like, ‘Oh, she’s crazy. She was just crying and now she’s laughing.’ Like, I make people nervous.”
But would the Ghostbusters star be game to reboot the movie?
Absolutely not, she says. “I wouldn’t touch it.”
