Leonard Nimoy's daughter is planning a documentary about the disease that claimed the actor's life.

Julie Nimoy and her fiance, David Knight, said this week they are developing a film to help those with chronic obstructive pulmonary disease, known as COPD.

In a statement, Julie Nimoy said the documentary will detail the latest COPD therapies and treatments. In retrospect, she said, her father would have benefited from such information.

Leonard Nimoy, best known as Mr. Spock in the "Star Trek" series and movies, died Feb. 27 from complications associated with COPD at age 83.

Last year, Nimoy used Twitter to announce he had pulmonary disease that he linked to a past smoking habit. In January, he tweeted a caution that read: "Don't smoke. I did. Wish I never had."
