Mr. Lesin’s son, Anton, began to make his mark in Hollywood not long after. The son, who Anglicized his name to Lessine, and a partner, Sasha Shapiro, formed a film-financing company called Media Content Capital. And in 2012, they acquired a controlling stake in QED International, a film production and distribution company founded in 2002 by Bill Block, for $25 million. The company has since produced a series of major movies such as “Fading Gigolo,” with John Turturro and Woody Allen; “Fury,” with Brad Pitt; and, most recently, “Dirty Grandpa” with Robert De Niro and Zac Efron.
