I searched the Internet for lists of the best whodunit 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 Ranker.com).

I was able to find 24 lists. I took the 24 lists and added all their content into a spreadsheet, noting the rank of every film. I ended up averaging the rankings each movie got (there were 144 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 24) were:

  • Knives Out (2019) – 22 lists
  • Clue (1985) – 21 lists
  • Murder on the Orient Express (1974) – 14 lists
  • Zodiac (2007) – 14 lists
  • Gosford Park (2001) – 14 lists
  • Rear Window (1954) – 13 lists
  • The Last of Sheila (1973) – 11 lists

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