NEW YORK — NBC has made it official: Michael J. Fox is coming back to series TV more than a decade after he left to concentrate on fighting Parkinson's disease. His new comedy series, based loosely on his personal life, has a 22-episode commitment from NBC and is set to premiere in fall 2013, the network announced Tuesday. The single-camera comedy, thus far untitled, will feature Fox as a husband and father of three from New York City who is dealing with family, career and challenges that include Parkinson's, the network said. No further casting was announced. — AP
