Mr Reapers official guide to a good movie plot:
Step1: always write down any ideas, anything that pops into your mind and makes you think "hey that would be a good movie" write it down, this is especially true when you think a comical or cool way of expanding on a hit movie like Star wars or the matrix, people love a good movie parody "key word GOOD"
Step 2: try to think outside the box, a good example of this was, a few weeks ago someone made a flash about what would happen if links friends sent him back to school, I thought that flash was so original, I recently came up with a movie plot about " why the poison mushroom really killed mario, how it goes is Mario eats the poison mushroom, then all of his organs and white blood cells start to attack the mushroom, so it fights back in a mario style of combat and wins thus killing mario," I think that is a pretty good plot for a movie, and if anyone makes that movie without permission, I will have proof, by this post that I came up with the idea
Step 3: a good comedy is always a hit, just make sure that it is not unoriginal, try to come up with your own ideas
Step 4: try to go into as much detail with your writing, dont slack off, trust me your movie will end up so much better in the end, this is especially important when you are sending your plotline or script to another user for them to animate
Step 5: If you cant aniomate or draw, dont even attempt to make it, all it will do is ruin the movie which could be good, and also if you make it and it gets blammed then you post the plotline or script for someone else to animate, it will make the movie look worse than it really is because the audience will have seen the idea already
Step 6: If you can, always make a possibility of a sequel, If your flash is a hit then your other movies are garaunteed to get through the portal if they use the same good idea, just be sure to end your series before the idea gets to old.
End
