A DYING Star Trek fan with only weeks to live has been given a private screening of the franchise's new film, after a Reddit post caught the attention of director JJ Abrams.

User ideeyut posted a callout for his friend Dan, saying his 41-year-old friend was suffering leukemia and desperately wanted to see Star Trek Into Darkness, or at least the nine-minute trailer that had been screened before some showings of The Hobbit.

The new film isn't due for release until May, but according to the posts, Abrams called Dan's wife and arranged the private screening for the dying fan.

Dan's wife was quoted in the post, saying, "There is nothing left to do but make him comfortable, at 41, he is jaundice & his liver is enlarged, his body has had enough, he has weeks to live."

According to the post, he was diagnosed with leukemia when he was 38, and had since been ravaged with more aggressive cancers.

The post was flooded with users posting contact details for the film studio, and offering to get in touch with contacts in Hollywood to make Dan's wish come true.

The original plea was posted on a Star Trek page of Reddit on Christmas Day, and was followed up on Saturday with this:

"He got to see it a couple of hours ago and loved it. JJ Abrams is the man. I'm going to buy an extra ticket for Dan when it comes out."
