Trekkies have boldly gone beyond the call of duty and hit the $600,000 funding target for a new documentary about the late Leonard Nimoy which is being produced by his son.

Adam Nimoy has offered fans a "sci-five" after his Kickstarter campaign to finance For The Love of Spock went into warp drive and hit its goal after just four weeks.

The film will honour the late Star Trek star, who died in March, on the 50th anniversary of the sci-fi series, which first aired on September 8 1966. For The Love of Spock will be narrated by Zachary Quinto who plays Spock in the current movie reboot of Star Trek.

The project launched on June 3 and has raised $634,000 from over 9,000 backers. Adam Nimoy said: “Rest assured: every dollar raised through this campaign will find its way to funding this film or helping in the promotion and advertising campaign.

"But the more we can raise, the better the end product will be. This film is a once in a lifetime chance and I want to give it all I have to give.”

Nimoy says that the funding will enable him to continue filming interviews with his father's friends, colleagues and family members and to license hundreds of film clips and still photographs of Mr Spock from his TV and film appearances over the last 50 years.
