Somethings missing

Question

In the puzzle below I've correctly placed an image in three different cells. Your task is to correctly place images in all the remaining (19) cells and of course, as usual, provide a good explanation why it's correct.

The other two: 2015, 2022

Answer 1

The empty cells should be filled as follows:

Because the man in the original image is:

Mohana Krishna Indraganti, director of the 2020 movie, V.

If we notice that:

'V' is the Roman numeral for '5' then count up the slots in the top image, we can see that there are sufficient spaces available to enter in the Roman numeral representations of all the numbers 1-9 (I, II, III, IV, V, VI, VII, VIII, IX). Moreover, the bottom image looks very much like it might be describing a magic square (horizontals, verticals and diagonals all indicated), with a sum of 15.

The positioning of this man's image confirms this - we can find a valid possibility that we probably need to complete:

Top row: 2, 7, 6
Middle: 9, 5, 1
Bottom row: 4, 3, 8

Or, in Roman numerals:

II, VII, VI
IX, V, I
IV, III, VIII

Note that these characters correspond perfectly with the available slots.

So what to fill it with? Thematically - and making use of the line saying "The other two: 2015, 2022" - we can find:

movies called 'I' from 2015 (directed by S. Shankar), and 'X' from 2022 (directed by Ti West).

So if we use the directors' faces to represent the Roman numerals from their movie titles, we can complete the puzzle as in the image at the top of this answer, with digits 1-9 appearing in the magic square and 'XV' (15) in the puzzle key to show what each run of 3 digits should sum to.
