‘Wild Horse Nine’ Casting Director Sarah Finn on What Made John Malkovich a Perfect CIA Agent and Why Chadwick Boseman’s Marvel Audition Still Feels ‘Emotionally Loaded’

Casting director Sarah Finn says *Wild Horse Nine* brought John Malkovich and Sam Rockwell together as CIA agents sent from Santiago to Easter Island, where their troubled pasts and new relationships unsettle the mission. She describes Malkovich as especially suited to a role that calls for quick shifts between humour, danger and regret, and says the cast’s chemistry and understanding of Martin McDonagh’s darkly funny writing were central to the process.

Finn says casting involved studying Chilean history and seeking local talent alongside established actors, with each role developed carefully. She also reflects on her long work assembling Marvel casts since *Iron Man* in 2008 and on Chadwick Boseman’s audition, which remains emotionally significant to her.
