While many people may not know Chet Harrell by name, they’ve likely seen his face, especially in film and TV projects shot in Louisiana the last few years. That dapper gentleman just to the right of star Harry Hamlin (Cortland Mayfair) in AMC’s Gothic drama series “Mayfair Witches”? That’s Harrell as Marcus Mayfair. The scene in 2023 docudrama “The Iron Claw” where Zac Efron as Kevin Von Erich is seeking a bank loan? Harrell’s the office manager.
