'Untold' trailer: Caitlyn Jenner reflects on sports career, identity issues

Aug. 18 (UPI) -- Netflix is giving a glimpse of the new documentary film Untold: Caitlyn Jenner.

The streaming service shared a trailer for the film Wednesday featuring Olympic gold medalist and television personality Caitlyn Jenner.

In the preview, Jenner reflects on her sports career and struggle with identity issues.

"I've always had these issues going through me. But without them, I don't think I ever would have accomplished what I did," Jenner says.

"I've just always dealt with confusion in my soul," she adds. "But when sports came around, it became the place where I could shine. That changed everything. So I built this Bruce character and I trained 365 days out of the year, because I needed to prove myself."

Jenner ended up winning a gold medal in the men's decathlon at the 1976 Montreal Summer Olympics.

"If I can win an Olympic gold medal, I can prove these issues don't exist," she recalls thinking. "But I was still the same old person with all the same old issues."

Jenner came out as a transgender woman in 2015.

Untold: Caitlyn Jenner is a new installment in Netflix's Untold series of documentaries, which explore iconic sports moments. The first episode, Untold: Malice at the Palace, examines the 2004 Pacers-Pistons brawl and was released Aug. 10.
