Watch: Greg Louganis in 'Thicker Than Water'

The 14-minute film "Thicker Than Water" debuted this week on ESPN.com, and it takes a look at former Olympic diver Greg Louganis' tough decision to compete in the 1988 Games after finding out that he was HIV positive, and the support system his coach provided during that difficult time.

In this moving documentary directed by Jennifer Arnold, Louganis and his coach, Ron O'Brien, open up about those excruciating days, and the leaps of faith that they both took to make history.

The film will air Friday, Dec. 6, on SportsCenter in the 6 p.m. ET hour as part of Friday Night Movie Night. Watch the short film below:
