'Once Brothers' - Vlade Divac and Drazen Petrovic.

Here's a fantastic documentary from ESPN's 30 For 30 program, titled 'Once Brothers'.

This episode focuses on the story of two star NBA basketballers, Serbian Vlade Divac and Croatian Drazen Petrovic.
It is set around the early-1990's and showcases how their once-close friendship becomes tattered following the outbreak of the Yugoslav war in 1992. It also covers Petrovic's shock and sudden death in July of '93.

Seventy minutes long, but an absolute must-watch.
