Rover (or Beyond Human: The Venusian Future and the Return of the Next Level).

In their dilapidated church headquarters, a dispirited cult awaits the sign to off themselves. Their hapless leader, Dave, concocts a plan: to quell infighting and give them purpose in life, he fakes a prophecy instructing them to make a movie and share their story with the world. They don't know the first thing about film production, but in making the movie the cult members find a uniting purpose. Then, just as they hit their stride, Dave receives a true prophecy. It's time for them to "exit."
