the hitmen on a supply shuttle from the other side of Jupiter. Realizing what is coming and with only Dr. Lazarus willing to help him, O'Niel sends a message to his family promising to return to Earth when his "job is done". O'Niel ambushes the hitmen one by one. Lazarus helps him kill the first by trapping him in a pressurized corridor; O'Niel activates a bomb, causing an explosive decompression that kills the hitman. The second is killed in a glass greenhouse structure of the outpost when O'Niel tricks him into shooting a window, causing it to break open and blow him out to his death by explosive decompression. O'Niel is then confronted and attacked by Sheppard's inside man - one of his own deputies, Sgt. Ballard. The two fight outside the outpost near the satellite structure until O'Niel pulls Ballard's oxygen hose, suffocating him as he pushes him into an electrical generation station, vaporizing him on impact. O'Niel then confronts the surprised Sheppard inside the outpost's recreation bar, knocking him out with one punch. It is implied Sheppard will now be brought to justice or murdered by his own associates. O'Niel, however, has already contacted his superiors about Sheppard's associates, some of whom are Con-Am executives, and shortly before his departure receives a communication that warrants have been issued for their arrests. O'Niel bids farewell to Lazarus and leaves on the shuttle to join his wife and son on the journey back to Earth. Cast Production Development Hyams recalled, I wanted to do a Western. Everybody said, 'You can't do a Western; Westerns are dead; nobody will do a Western'. I remember thinking it was weird that this genre that had endured for so long was just gone. But then I woke up and came to the conclusion – obviously after other people – that it was actually alive and well, but in outer space. I wanted to make a film about the frontier. Not the wonder of it or the glamour of it: I wanted to do something about Dodge City and how hard life was. I wrote it, and by great fortune Sean Connery wanted to do it. And how many chances do you get to work with Sean Connery? The film was developed at Universal by Hyams and producer Richard Roth. Universal turned it down then Roth, who had a development deal at 20th Century Fox
