Iraqi director nominated at Directors Guild of America Awards for ‘The President’s Cake’

DUBAI: Iraqi director Hasan Hadi this week received a Directors Guild of America Awards nomination for Outstanding Directorial Achievement in First-Time Theatrical Feature Film for his debut, “The President’s Cake.”

Hadi’s film is shortlisted in the category alongside Eva Victor for “Sorry, Baby,” Alex Russell for “Lurker,” Charlie Polinger for “The Plague,” and Harry Lighton for “Pillion.”

Also in the running for Outstanding Directorial Achievement in a Theatrical Feature Film are Guillermo del Toro for “Frankenstein,” Chloe Zhao for “Hamnet,” Ryan Coogler for “Sinners,”Josh Safdie for “Marty Supreme,” and Paul Thomas Anderson for “One Battle After Another.”
