As his offbeat movie “Ferris Bueller’s Day Off” became a hit, Matthew Broderick vacationed in Northern Ireland with his co-star and then-girlfriend, Jennifer Grey, in the summer of 1987. On Aug. 5, Broderick’s car veered off a rain-slicked road near the town of Enniskillen and collided with an oncoming vehicle.

Killed were Anna Gallagher, 30, and her 63-year-old mother, Margaret Doherty. An unconscious Broderick had to be cut from the car. Jennifer suffered only scratches. The actor spent a month in the hospital with a fractured thigh and claimed to have no memory of the crash.

Charged with causing death by dangerous driving, Broderick was eventually convicted only of careless driving and fined $175.

Now married to Sarah Jessica Parker, he will never forget one headline that expressed the feeling of the deceased’s survivors: “Ferris Bueller’s Let Off.”
