Winona Ryder and Gabriel Byrne
The lead character, Jo March, portrayed by Winona Ryder, and an older professor, Friedrich Bhaer, portrayed by Gabriel Byrne, develop romantic feelings for one another throughout the events depicted in the film adaptation of Little Women from 1994. Actors play the roles of Jo and Friedrich Bhaer in this production.
But Ryder is the one who plays Jo and Byrne is the one who plays Friedrich Bhaer. Gabriel Byrne was 44 years old when they met in real life, whereas Winona Ryder was only 22 years old at the time. Given these ages, it is clear that Gabriel Byrne is precisely twice as old as Winona Ryder.
