Polly Platt, a producer, Oscar-nominated production designer, writer -- and ex-wife of filmmaker Peter Bogdanovich -- died Wednesday morning in Brooklyn, NY., according to published reports. She was 72 and had ALS, also known as Lou Gehrig's Disease.

Platt was nominated for an Oscar for set decoration for the 1983 movie "Terms of Endearment."

As recently as this year, she executive produced the documentary "Corman's World: Exploits of a Hollywood Rebel." Her other credits include producing the 1989 film "Say Anything" and executive producing the 1987 movie "Broadcast News."

As a production designer, she worked on Bogdanovich's "Targets," "The Last Picture Show," "Paper Moon" and "What's Up Doc." On the set of "The Last Picture Show," however, her marriage to him collapsed.

In fact, the 1984 film "Irreconcilable Differences" was loosely based on her divorce.
