The Beatles stormed through Europe's music scene in 1963, and, in 1964, they conquered America. Their groundbreaking world tours changed global youth culture forever and, arguably, invented mass entertainment as we know it today. All the while, the group were composing and recording a series of extraordinarily successful singles and albums. However the relentless pressure of such unprecedented fame, that in 1966 became uncontrollable turmoil, led to the decision to stop touring. In the ensuing years The Beatles were then free to focus on a series of albums that changed the face of recorded music.

Billy Preston: That's the Way God Planned It
10.0

With his signature gospel sound on the Hammond B3, Billy Preston doublehandedly elevated the greatest artists of his time – from the Beatles to the Rolling Stones, from Aretha Franklin to Eric Clapton, from Ray Charles to Barbra Streisand to Sly and the Family Stone. In our film, we explore Billy's career and influence on generations of musicians, as he scored several number one hits of his own and became one of the most sought-after musicians in the world. He did all of this as a soul divided -- by his deep roots in the church, in constant conflict with his identity as a gay Black man, searching for a family of his own that would accept him for who he was.

MOLE MAN follows RON, a 66-year-old autistic man who has spent the last five decades building a 50-room structure in his parents' backyard. Using no nails or mortar, Ron instead creates perfectly balanced structures from scavenged materials he finds in the woods outside his Western Pennsylvania home. When Ron's father passes away, leaving him living alone with his 90-year-old mother, Ron's siblings are left to figure out what's best for Ron - who has never been officially diagnosed with autism - when his mother can no longer care for him. In an effort to find the money to keep Ron in his home, his friends team up in search of a mythical mansion Ron insists lays abandoned in the forest. But will they be able to find it? And, more importantly, does it even exist? This is the story of an extraordinary life, a family, and the beauty of thinking differently.
