Armstrong is writing the untitled movie for HBO Films based on an original idea. He is executive producing it with Frank Rich. The duo, both under overall deals at HBO, also executive produced together Succession.

Details are scarce but the film is said to revolve around four friends who meet up during the turmoil of an ongoing international financial crisis.

Armstrong is still writing the script but the movie is being fast-tracked, with cast availabilities being checked for a production start later this year.
