A New Mexico woman is suing 20th Century Fox Film Corporation alleging she was defrauded out of $4.4 million she was entitled to receive for the popular 1960s "Batman" television series.

Deborah Dozier Potter, whose father William Dozier was one of the producers of the show, filed the lawsuit Wednesday in Superior Court that alleges fraud, concealment and breach of contract.

She is an heir to her father's estate and holds a portion of the assets of Greenway Productions Inc. which produced the series four decades ago that Fox distributed, according to the lawsuit.

Both companies, Greenway and Fox, signed a contract in the 1960s, the lawsuit said. Another contract was also signed between Fox and ABC, the station which televised the show. In March 2005, Potter came across the agreement between Fox and ABC and discovered she was entitled to 26 percent of the net profits from that agreement as well.

"I wish it could have been avoided," Potter said from her home in Santa Fe. "Nobody likes litigation."

Fox does not comment on pending litigation, said Chris Alexander, vice president of 20th Century Fox Television.
