Star Trek legend William Shatner will pay homage to his friend and co-star Leonard Nimoy in a book about the late actor's life.
Shatner, 84, starred in the iconic sci-fi series as Captain James T. Kirk, opposite Nimoy's half-human half-Vulcan science officer Mr. Spock, and now Shatner is going to honour his "brother" in print.
Shatner told The Guardian newspaper: "I'm writing a book about Leonard. I had a brother, whose life arc was so much like mine that we understood each other completely. Our age, our birth, the same types of problems in our marriages - our careers arced in the same manner. "
Nimoy and Shatner acted together for seven series set in the 23rd century on the USS starship Enterprise from 1966 to 1969.
Nimoy - who was 83 when he passed away in February this year - went on to star in another hit TV series 'Mission: Impossible'. He also won acclaim in stage shows Fiddler on the Roof and One Flew Over the Cuckoo's Nest in the 1980s.
