"Life is about these moments that flash by but stay in your heart forever," says Brolin's character in the spot, featuring Key & Peele's Jordan Peele. The show’s first episode tells the story of one family through separate vignettes as they eventually come together in the end.

Reassuring Brolin, Wiests character mistakenly adds, "70 is the new 80!"
