Dear Moro:
To shoot a movie, you first need a story line. Then it has to be written to text of individual speech, replys, and where do you from for where ever you want to go. If this is non commerical, then I presume that you will be shooting with video cam, not a 35,16, or 8mm cam. If you shoot with the non video cam. You'll need at least three cams. Two stationaryand one to roam.
Your begining of the story is conceptually good. A lot can take place from there. Locations may be key for you in making your better than average home movie.
