Passion + Experience


Markos Rounthwaite and Miram Choi united their creative passions after meeting in Los Angeles during the formative years of Markos' action design company, MR Stunts Inc.

Leveraging over two decades of award-winning stunt coordination and martial arts experience, Markos brings a gritty, in-the-trenches directorial style to every project. Miram lends her diverse interior & design background, along with logistical talents honed on major studio productions like Iron Man 3, Sherlock Holmes and The Gunman where they collaborated on action design and second unit directing.

With decades of on-set experience, and now a dual base in USA and EU, Markos and Miram steer their formidable talents towards creating original film and television content for global audiences. Backed by extensive credentials yet nimble as an indie outfit, Markos & Miram are intent on Greenstone Films developing each project with a raw, organic aesthetic true to the emotional heart of the story, bringing both the spectacular and human elements to life on screen.
