“Sharper” opens with a fake out—in its own title. A dictionary definition fades up on the screen, declaring “sharper” as a noun that means “one who lives by their wits.” This little bit of cheeky word play is a harbinger for the never-ending rug pulls and elaborate deceptions to come in this con artist thriller, directed by longtime TV director Benjamin Caron and written by the team of Brian Gatewood and Alessandro Tanaka.
