"It could have been me, and it was her," she said.

"Russian roulette in a way, because you can die and through no fault of your own.
You get cured only because of where it is, what it is, when they find it.
And the cure is much better the sooner you find it," she added.
Archival Footage and Honest Portrayal
The film uses historical archival footage to explore their 80 head-to-head matches. Navratilova held a narrow 43-37 advantage after trailing early in their careers.
Navratilova noted that she was only really close friends with players who could never beat her.
The documentary reveals how archival interviews captured an era of intense, unpolished interactions between the two competitors.
When both women received clear medical scans during a joint screening session, the deep bond forged through decades of competition became undeniable.
Navratilova described them as "bound souls."

Skipper explained that the project succeeded because it moved beyond standard archival sports recaps.

"It's a formula to draw an audience, but this was a bit of a return to making documentaries that are about something that transcends sports," he said.
