Little Tito and the Aliens (2018)

Grieving and withdrawn, Professor Biondi hides from the world in a Nevada desert shack near Area 51. His top-secret government job is a sham; he just lies on the couch, listening to the hum of the cosmos. His only human contact is Stella, who runs alien-themed weddings for UFO-chasing tourists. Then a message from Naples shatters his solitude: his dying brother has entrusted him with his two children, who are coming to live with him in America.
