Ben Affleck will star as a maths savant cooking the books for dangerous clients when his new film The Accountant premieres in London today.
The Gone Girl actor plays Christian Wolff in the crime drama, which also stars Anna Kendrick and Oscar winner JK Simmons.
Wolff uses his small-town accountancy office as a front for his freelance work for criminal organisations.
Affleck, who is currently in pre-production on the Batman movie he will star in, write and direct, entitled The Batman, will walk the red carpet at the Cineworld Empire, Leicester Square, alongside Kendrick and director Gavin O'Connor.
The Accountant is released in the UK on November 4.
