I have no idea what's being displayed at the convention.
But traditional film-noir titles would be "Kiss Me Deadly", "The Maltese Falcon", "Night And The City", "Citizen Kane"(?), "The Naked City", "He Walked By Night", etc.
Relatively modern examples (neo noir) would include but not limited to:
BODY HEAT
THE LAST SEDUCTION
CHINATOWN
DIRTY HARRY
NIGHTCRAWLER
LA CONFIDENTIAL
