Going outside its executive ranks, Warner Bros. Entertainment has selected former NFL exec Kim Williams as executive VP and chief financial officer.

She replaces Ed Romano, who was promoted to vice chairman on Wednesday after two decades as CFO. She will begin working at the studio Jan. 15.

The announcement was made by chairman-CEO Kevin Tsujihara. She will have responsibility for all financial activities, including financial reporting, budgeting and planning for future business growth. She will report to Tsujihara and work closely with the corporate officers and senior management.

“As our industry’s financial sector becomes much more complex and nuanced, it’s crucial to have strategic, intelligent and thoughtful financial leaders,” said Tsujihara. “Kim is a proven finance pro with an impressive track record and a background that fits perfectly with our needs. Ed left big shoes to fill, but I believe Kim is more than up to the task.”

Williams served as CFO for Core Media Group and chief operating officer of NFL Network, overseeing the league’s cable TV operations and NFL facilities and studios in Culver City. She also previously served as CFO for the NFL.

Williams also has served as senior VP and CFO for NBC West Coast.

The studio has also promoted Reg Harpur to the post of executive VP of operations and planning. Tsujihara said Harpur will be part of the “ambitious” goals he’s set both operationally and financially.

Prior to his promotion, Harpur served as senior VP and controller, a post to which he was promoted in 1994. He was responsible for managing Warner Bros.’ worldwide finance and accounting staff of more than 1,000 along with managing near-term and long-range financial planning, as well as its treasury, tax and financial compliance functions.
