Alcon Entertainment is looking for a top TV executive now that Sharon Hall has departed the company after a little more than three years in the post.

Hall and Alcon principals Andrew Kosove and Broderick Johnson could not come to terms on a new contract for Hall to continue as Alcon TV president, the company said in a statement.

“Sharon has been an instrumental, guiding force in shepherding Alcon Television’s accomplishments in a brief period of time. We whole-heartedly wish her the best with her new endeavors,” Kosove and Johnson said.

Alcon TV’s slate of projects includes the upcoming Syfy series “The Expanse” and Alex Gibney’s four-hour HBO docu “Sinatra: All or Nothing at All,” which just landed an Emmy nom for nonfiction special.

Also on deck is a DirecTV series, “Ice,” from film vet Ron Bass and director Antoine Fuqua. Alcon is producing and financing “Expanse” and “Ice,” which makes it the rare indie banner to fund its own productions.

Before joining Alcon Hall was an exec VP overseeing drama for Sony Pictures TV.

On the film side Alcon is known for producing such hits as “The Blind Side” and “Dolphin Tale.”
