A Ticket to Space (2006)

Stéphane, an unemployed comedian, receives a winning lottery ticket from his son, offering two civilians the chance to stay in the European orbital station with a professional crew. This is how Stéphane suddenly finds himself in training with the other winner, Yonis, a former pilot forced into hiding since his brother, a serial killer, is in prison. Stéphane and Yonis take off under the orders of Commander Beaulieu, his teammate, Soizic, and a scientist specializing in poultry. Everything goes well, until Yonis takes the station hostage.
