No doubt many of you know Ron Livingston best for playing Peter Gibbons in the 1999 comedy Office Space, or perhaps you remember him best from his time as Captain Lewis Dixon in the HBO miniseries Band of Brothers. As far as Livingston’s more recent work goes, he’s appeared in movies like Tully, The Professor and The Man Who Killed Don Quixote, while on TV, he currently stars in the Amazon Prime Video series Loudermilk and recurs on the ABC series A Million Little Things. Given that The Flash movie is adapting elements of the Flashpoint storyline, it makes since that the production brought Livingston to fill in as Henry Allen rather than simply remove the character, as well as cast Ian Loh as Barry Allen in his childhood years.
