On the Comet (1970)

When a comet passes the Earth at close range, it pulls a small part of North Africa with it. Carried along are a bunch of people, among them Angelika, who has just escaped from a ruthless weapon dealer's ship, and her two brothers, who are searching for her. Then there's a group of natives planning a rebellion against the French colonists. All conflicts become secondary when the people finally realize that they're doomed to live together on an alien planet. However, this time of peace and happiness won't last for long...
