Should be an easy one for the experts, title should explain it all, but cop thinks he has fatal disease and 6 months to live, (because of mix up at doctor), also if he dies in action his family gets more money, so he takes many crazy risks during his work as a cop. Sorry can't even picture the lead actor! Please name this movie for me!

Thanks,
Sean
