The Observer presents a preview screening of Kelly Reichardt's The Mastermind, in partnership with Mubi. Limited free tickets are available for Observer subscribers. We will confirm your Observer subscription and booking confirmation by email. General tickets go on sale on Wednesday 20 October. In a sedate Massachusetts suburb circa 1970, unemployed family man and amateur art thief J.B. Mooney sets out on his first heist. With the museum cased and accomplices recruited, he has an airtight plan. Or so he thinks. Be among the first to see The Mastermind, followed by a Q&A with award winning actor Josh O'Connor, in conversation with the Observer's film critic Wendy Ide.
