In the movie class of 2016, “The Accountant” was a wild-card.

It told an original story for adults, breaking from the family-friendly intellectual property derivatives that crowded the top of the box office charts. And though it resembled a durable breed of man-on-a-mission action thrillers, it had an absurdist, gleefully dorky twist — Ben Affleck playing a neurodivergent bookkeeper and consigliere to the criminal underworld.

Audiences responded. “The Accountant” outperformed expectations in theaters, earning $155.5 million globally (according to Box Office Mojo), and was the No. 1 most rented movie of 2017 (according to Comscore), ahead of “Moana,” “Wonder Woman” and “Rogue One: A Star Wars Story.”

Nine years and a change of studios later, a sequel, “The Accountant 2,” arrives on Friday, with Affleck and much of the original cast (Jon Bernthal, J.K. Simmons, Cynthia Addai-Robinson) returning, along with the director Gavin O’Connor and the screenwriter Bill Dubuque. In two conversations — one at South by Southwest in March, before the film’s premiere there, and another virtually earlier this month — Affleck, O’Connor and Dubuque discussed regaining the rights to the story, the definition of success and a potential idea for a third film.

These are edited excerpts from the conversations.

Bill, you wrote the script for the first “Accountant” independently — before an actor or a director was involved. Where did the main character, Christian Wolff, come from?
