I searched the Internet for lists of the best or greatest alien movies of all time. Criteria included the movies being ranked, not just listed, and generally created by groups, whether teams or committees or based on general public voting (like

I was able to find 13 lists. I took the 13 lists and added all their content into a spreadsheet, noting the rank of every film. The total number was over 600 including all the repeats. I experimented with different formulas, trying to balance the value of being ranked high on any list and being included on the most lists. I ended up averaging the rankings each movie got (there were 117 that were on at least 2 lists) and dividing that average by a factor of the number of lists that movie was on. The lowest score meant a high ranking average on many lists. The complete spreadsheet is attached at the bottom.

The movies that were on the most lists (out of 13) were:

  • The Thing (1982) – 10 lists
  • Close Encounters of the Third Kind (1977) – 10 lists
  • District 9 (2009) – 10 lists
  • Independence Day (1996) – 10 lists
  • Predator (1987) – 9 lists
  • Arrival (2016) – 9 lists
  • They Live (1988) – 9 lists
  • Edge of Tomorrow (2014) – 9 lists
  • War of the Worlds (2005) – 9 lists
  • Attack the Block (2011) – 9 lists

Here are links to the lists I used along with dates the lists were created:
