Actor Zachary Quinto has written a touching article to commemorate Star Trek star Leonard Nimoy, who died last week.
Nimoy, who played Spock in the sci-fi series, died aged 83 after a battle with chronic obstructive pulmonary disease.
Quinto, who played Spock in JJ Abrams recent Star Trek movie, bonded with Nimoy when he took over the role.
He says the veteran actor became a father-figure to him.
