I have decided for today to cast a science fiction movie. The plot is that the new captain has stepped into the position of taking over the most important star ship humanity has. The older crew has remained on the ship in order to help train him and the new crew but unexpected problems arise. Harrison Ford A clear choice for this movie, he will probably take role of the rogue officer who doesn't follow orders and would have been fired long ago if not for the skill with which he performs his job. Patric Stewart My first thought for captain I suspect that it would be predictable and in a movie the captain is likely to be more of an action role so I see Patric Stewart as the science officer. Anthony Hopkins With this cast there are few people who could pull off a truly believable threat and this would be my first choice for the job. There is no doubt that he can pull of an intense and scary villain. Arnold Schwarzeneger Security officer of the ship, he wouldn't have a lot of lines but those he did say would be important, and not puns or jokes. Nathan Fillion The young new captain, he is brash but brilliant. He spends much of the movie attempting to convince the older members of the crew that he is the correct person to be in charge of this ship.
