The CEO of Ron Howard and Brian Grazer’s Imagine Entertainment production company has exited the firm and plans to start his own media company, according to The Hollywood Reporter. Charlie Corwin departs after joining the company as CEO a little more than a year ago.

“Corwin, who previously served as co-chairman and co-CEO of Endemol Shine North America, was brought aboard Imagine in January 2017 in the newly created position of CEO, reporting to Imagine partners Brian Grazer and Ron Howard,” THR notes. “The exec had worked at Endemol Shine since 2007 and exited in fall 2016.”

Imagine co-Chair Michael Rosenberg said Corwin made the decision to step down in December. In a statement, Rosenberg said: “We think Charlie is smart and talented, and we want to be in business with him going forward and so we’ve made an investment in the company he is putting together.”
