Phase I: Group each of the 27 names into 9 groups of 3 each. Name the movie that all 3 were in. Name a 4th actor from each movie (there is only one right answer, and many wrong ones). This will leave you with 9 names.
Phase II: Group the 9 names into 3 groups of 3, as in phase I. Name a 4th actor, which will give you 3 new names.
Phase III: Group them into 1 group of 3. What is the movie?
