In the end, documentaries are only as good as the access filmmakers get.

Radovich and Karasik declined to discuss "final approval" of what's in or out of the film, but they say they had "fly-on-the-wall" access to the lives of the cadets and midshipmen.

"When we came to them, they looked at it as a great opportunity to showcase their schools," says Radovich, who also serves as co-coordinating producer of Showtime's critically acclaimed series "Inside the NFL."

"As far as limitations, there were none. From a football standpoint, we were given access to locker rooms, sidelines, practices, meetings rooms. It was all in."

The difference, he said, was in access to the athletes' "lives away from the football field."

"Frankly, we were surprised at times how far in they let us go," Radovich said. "Some of the moments when we're out in the field when they're doing their military training, it feels like this isn't even a documentary. At times, I watch it and think, 'This feels almost like feature film.'"
