Leonard Nimoy’s daughter Julie Nimoy and husband David Knight are launching a crowdfunding campaign on Indiegogo about the “Star Trek” star and the disease that led to his death.

The couple is seeking $150,000 to complete production on “COPD: Highly Illogical” — a combination of a tribute to Nimoy and an exploration of chronic obstructive pulmonary disease, the cause of his passing last year at age 83. They plan to make “Highly Illogical” available free for downloading.

The project already raised $300,000 through corporate sponsors. Premiums in the new campaign include dinner with the Nimoys for $5,000 and an associate producer credit for $10,000.

The movie is aimed at providing information and treatments on COPD from medical experts along with examining how COPD affected Nimoy. The film’s narration is provided by John de Lancie, who starred on “Star Trek: The Next Generation” and other spinoff series as the character “Q.”

“It was his mission to do this during his last few months,” Julie Nimoy said. “We also want to be entertaining and engaging.”

Julie Nimoy’s brother Adam Nimoy is also using crowdfunding to make “For the Love of Spock,” a look at the iconic role that their father originated. That project, which raised $662,640, is narrated by Zachary Quinto with interviews with William Shatner, George Takei, J.J. Abrams and Seth MacFarlane.

Both films are aiming to be tied in with the 50th anniversary of “Star Trek” this year. The first show aired on Sept. 9, 1966.

Julie Nimoy told Variety that the “Highly Illogical” title was taken from a reaction that the Spock character often used when perplexed by human behavior.

“We also wanted to show that the people’s reaction to COPD is often highly illogical,” she added. “There are probably 12 to 15 million people in the U.S. who have it and yet a third of them continue to smoke.”
