“This Amount of Time” (formerly “Revisiting Utopia”) is the real-life story of how growing up in an integrated community shaped the experiences of Black, white, Asian and Latino kids in the 1960s, ’70s & ’80s. It is a stark portrait of the segregation of America’s housing and schools — and the unusual, sometimes questionable means Park Forest used to overcome it.

The film depicts how a series of Facebook posts led members of each race to reexamine their experience and reframe their perspectives as adults — and their conclusions about the racial harmony many said they experienced. Both messy and glorious, the lasting impact can be seen and heard in the eyes and words of those who experienced it.
