Leonard Nimoy's charitable spirit has been passed down a generation from one Spock to another. Zachary Quinto currently plays Spock -- a role Nimoy made famous in the original "Star Trek" series -- in J.J. Abrams' "Star Trek" movies. Quinto led the cast of the upcoming "Star Trek Beyond" in a tribute to Nimoy during a charity video to promote a campaign for the St. Jude's Children's Research Hospital, a cause Nimoy personally championed before his death in February at 83 years old. 

The video is the final in a series called "To Boldly Go," which was produced by the "Star Trek Beyond" cast to highlight nine different charitable organizations. Each week, the cast has been releasing a video and requesting a $10 donation in return for a chance to win a walk-on role in the upcoming film. The ninth and final week focuses on Leonard Nimoy's charitable endeavor of choice -- St. Jude's Children's Research Hospital -- and features a tribute from Quinto to the original Spock. 

"Leonard was an actor, a champion of the arts and a true inspiration to so many," Quinto says in the video. "Through his legendary portrayal of Spock, he influenced countless scientists and artists, myself and the rest of the cast included. It was an honor and a privilege to know him and to call him a friend. Leonard's love for the human spirit shone through everything he did. He touched lives around the world, and he is greatly missed."
