Oliver Petkus is an American actor best known for his performance as the sidekick Best Buy Jones in "The Lame Ranger" (2023). Petkus was a member of the Haldane acting company from around 2019 to 2025, known for his youthful appearance and naive charm. He often played innocent characters such as Will Parker in "Oklahoma!" (2023), and the Baker in "Into the Woods" (2025). He was seen as "the kid" of the acting troupe, despite being one of its longest serving members, remaining a regular player after several key players left for other projects. Petkus's acting career slowed down after he left the Haldane troupe, but he did return to another Sam Bates picture with Bros Studios in 2026 in "Captain Bonanza!" as the henchman Bonzo.
