In the Star Wars sequel trilogy, spanning Episodes VII-IX, Kylo Ren is a conflicted figure who has given himself over to the Dark Side. In real life, however, it sounds like Adam Driver is a straight-up nice guy, according to this anecdote from Ben Affleck.

In a recent appearance on the Jimmy Kimmel show to promote the new basketball drama The Way Back, Affleck talks about Driver, who is his co-star in the upcoming Ridley Scott-directed film, The Last Duel. The film, which was co-written by Affleck and fellow co-star Matt Damon, is a historical drama about two men who are ordered to fight to the death.

At around the 7:35 mark in the video below, he begins talking about his son's recent birthday, and his rush home to see him for his eighth birthday. However, the presents he'd arranged for his son did not make the trip over, and Affleck was worried that he'd show up for his son's surprise birthday party empty-handed.
