ibetite, to initiate dialogue with potential buyers at AFM, all Mark needs is the trailer and some effects footage, and a copy of script for deeper inspection, if desired.
consider the analogy of a traveling salesperson who brings product samples to a conference to give potential buyers a sense of the products.
interested buyers may then get a current rough cut, so they have a crisper sense of the overall film's marketability before writing a check.
imo, the key take-aways are:
-- MIKP is presenting several films at AFM (and elsewhere), not just WS.
-- WS post will be completed in the next half year.
-- WS can be sold before completion.
