Which editor of Supergirl is a frequent collaborator of Craig Gillespie?

The Supergirl editor who is a frequent collaborator of Craig Gillespie is Tatiana S. Riegel.

Riegel edits Supergirl alongside Fred Raskin. Her connection to director Craig Gillespie predates this film: the pair have worked together on projects including Lars and the Real Girl, Fright Night, Million Dollar Arm, and The Finest Hours. That repeated partnership makes her the editor specifically identified as Gillespie’s frequent collaborator.

Riegel is an American film editor whose credits range across studio films, independent productions, television, and documentaries. She was nominated for the Academy Award for Best Film Editing for I, Tonya, the 2017 biographical drama directed by Gillespie. That film’s editing helped shape its rapid, fractured, and deliberately theatrical storytelling style.

The other options are accomplished editors but are linked primarily to different directors or franchises. Thelma Schoonmaker is closely associated with Martin Scorsese, Sarah Broshar has edited major contemporary studio films, and Maryann Brandon is known for collaborations including J. J. Abrams projects.
