How to play
- Tap four headshots you think appear in the same film, then press Submit.
- A correct group locks in and shows the film. Colours run from the easiest group (yellow) through green and blue to the trickiest (purple).
- You can make four mistakes. If three of your four are right, you'll be told you are one away.
- Every puzzle has exactly one solution, even though some actors appear in two or three of the films.
