JJ Abrams has revealed many Star Trek fans found the title he chose for the new film "odd".
The filmmaker spoke to Total Film about the sequel and reactions to its name, Star Trek Into Darkness.
Admitting it was odd, he said: "But my favourite thing about it was the first week it was out there, the fans were going 'Star Trek Into What? I don't understand it. It's stupid'."
"It definitely feels like the title's appropriate. This is a story about these characters being challenged and tested and taken to a place that's about sacrifice and life and death."
Abrams, 46, said he also likes that the title leaves room for ambiguity so as not to spoil any surprises.
He said: "I remember there was a movie, An Innocent Man , and I was like, doesn't that kinda ruin everything?"
The Star Trek sequel stars Benedict Cumberbatch and Simon Pegg.
Abrams is also signed up to produce the third Star Trek film, due out in 2016.
He created mystery TV series Lost, is directing Star Wars: Episode VII and has announced he will work on Mission: Impossible 5.
Star Trek Into Darkness opens on May 9.
