The three children of Frank Sinatra are at odds over a proposal to produce a theatrical documentary about the late singer's life, the Los Angeles Times reported on Sunday. The newspaper said that 59-year-old daughter Tina has been in discussions about a Sinatra film that would be directed by Martin Scorsese, who previously has helmed documentaries about The Band, Bob Dylan, and The Rolling Stones. He's also, like Sinatra, Italian-American. "He's really the only one to do it, isn't he?" Tina Sinatra remarked in an interview with the Times. Sister Nancy Sinatra, 67, however, is opposing the documentary venture, telling the Times that she is concerned that it would "dwell on the negative and ugly moments" of her father's life, to quote the newspaper. She said that she would prefer an eight- to 10-hour documentary that presumably would be shown on television as a miniseries. Brother Frank Sinatra Jr., 64, complained that he had been kept out of the loop by his sisters about the film and other matters related to his father's estate. "I'm not party to all those decisions, not like I would like," he said. The dispute came to light as the Times prepared a feature article about the singer, who died 10 years ago on May 14, 1998 and who is being honored with a postage stamp featuring his image this week.
