In the Uncharted video games, Richard "Sully" Sullivan is a treasure hunter who also serves as a father figure to Drake. Richard McGonagle provided the voice work for Sully in the games, while Stephen Lang portrayed him in a fan film that starred Nathan Fillion as Drake.

The Uncharted film features Tom Holland in the role of Drake and is currently filming in Germany, with coronavirus (COVID-19) health protocols in effect. Holland posted the first look of himself as Drake to Instagram, while official set photos on Twitter saw him meeting Drake's voice actor Nolan North. Uncharted underwent a rocky road to production, with several directors and screenwriters boarding and departing the Sony-backed project. Uncharted acts as a prequel to the games, with Holland playing a younger version of Drake.

Directed by Ruben Fleischer, Uncharted stars Tom Holland and Wahlberg alongside Antonio Banderas, Sophia Ali and Tati Gabrielle. The film is set to arrive in theaters on July 16, 2021.
