Alec Baldwin was announced as the lead when the film went into production but he was replaced by Aaron Eckhart by the time filming commenced.
As Malloy is joining his wife at the restaurant, the song in the background is "Think of Me" from Andrew Lloyd Webber's Phantom of the Opera, which is about a pure young woman enchanted by a haunted and dangerous man who lives in a world of shadows and deceit.
"Chief Of Station" will mark the second time actors Aaron Eckhart and Olga Kurylenko have worked together since the movie "Erased" in 2012.
Third time director Jesse V Johnson and actress Olga Kurylenko have worked together following White Elephant (2022) and Boudica: Queen Of War (2023).
The restaurant where Ben Malloy goes to meet John Branca is not GUNDEL but Felix. Gundel is actually close to the Zoo and Szechenyi Thermal Bath.
