This Oscars-themed special, hosted by Robin Roberts, takes a look back at the youth of nominated stars like George Clooney, Glenn Close, Viola Davis, Octavia Spencer, Gary Oldman, and others. It includes conversations with former costars and features childhood photos and home video. The show will also pay tribute to returning Oscars host Billy Crystal (pictured).
