LOS ANGELES - Jack Haley Jr., longtime Hollywood producer, actor and writer and the former husband of Liza Minnelli, died early Saturday morning. He was 67.

Haley, who had recently been in poor health, died of respiratory failure at the UCLA Medical Center in Santa Monica, Calif., Haley's longtime assistant Kelly Brandt said. Brandt said Haley had been admitted to the hospital on Friday in semi-comotose condition.

During a career that spanned more than 30 years, Haley produced numerous films and television specials including a number of Academy Award Shows and The Wonderful Wizard of Oz, a 1990 film documenting the making of the classic movie. He directed the box-office smash hit, That's Entertainment, a documentary about the golden age of the Hollywood movie musical.

He was the son of actor Jack Haley, who played the Tin Man in The Wizard of Oz, and in 1974, he married Minnelli, the daughter of Judy Garland, who played Dorothy in that film.

Haley and Minnelli divorced in 1979 but remained close friends.

I fell in love with him the first time I met him, and I have loved him with all my heart ever since, Minnelli said in a statement on Saturday.
