It may be interpreted as a reflexion about art itself…

… or imposture…

…or friendship…

…or mental illness…

…or values.

We may think that it is about dishonest bussiness, either cloth(es) or canvas…

…or uncovered fraud…

…or envy…

…or vanity…

But it really is a movie about passion…

…or obssession…

Whatever.
