The actor Lea Thompson has had a distinguished screen career but hesitated to share it with her daughters when they were growing up. “I did not show them most of my stuff because I end up kissing people all the time and it was traumatic to my children,” she recalls. “Even when they were little the headline was, ‘Mom is kissing someone that’s not Dad and it’s making me cry!’”
Thompson’s most celebrated role would be especially hard to explain. As Lorraine Baines in Back to the Future, she falls in lust with her own son, Marty McFly, a teenage time traveller from 1985 who plunges into 1955 at the wheel of a DeLorean car.
