May Theme: Decades (30 movies)
The goal is 5 movies each from 6 decades.

Everyone list 5-10 Sci-Fi/Fantasy films that others may have never seen. Then for the ones you watch for this category, mention who recommended the film in your post.

Movies about mothers or movies with strong maternal characters.

The remaining 10 movies/2 categories for the challenge are up to you to categorize however you want.

The Usual Fine Print:

• 50 movies is the goal, but based on your own time and situation you can shoot for more or less, so we have different levels from Coal to Platinum:
  60 Movies - Platinum
  50 Movies - Gold
  40 Movies - Silver
  30 Movies - Bronze
  20 Movies - Copper
  10 Movies - Coal
  <10 Movies - Why are you on this site?
• If you're going to re-post your entire list every time, please hide it under spoiler tags.
• If you're going to post pictures for the films (poster art or Blu-ray covers, for example) please try not to use GIANT pictures, and if there are tons of them, again - please hide under spoilers.
