Simon Stephenson sent an email to the Writers Guild of America’s senior director of credits Lesley Mackey asking to set up a call to discuss an important matter. The CAA-repped writer, whose credits include Pixar’s “Luca” and StudioCanal’s “Paddington 2,” wrote, “I’ve encountered a credits-related issue on quite a high profile WGA-covered project.” According to the email exchange reviewed by Variety, a call between the two took place, and, in a follow-up missive, Stephenson wrote, “the evidence the holdovers screenplay has been plagiarised line-by-line from frisco is genuinely overwhelming – anybody who looks at even the briefest sample pretty much invariably uses the word ‘brazen.’” Stephenson was referring to his own screenplay “Frisco,” a drama centered on a world-weary middle-aged children’s doctor and the 15-year-old patient he gets stuck looking after, and David Hemingson’s “The Holdovers” — a drama revolving around a world-weary middle-aged boarding school teacher and the 15-year-old pupil he gets stuck looking after.
