Matthew McConaughey has called Christopher Nolan's new sci-fi epic Interstellar "wilder than any other ride" seen on screen. Anticipation for the space-exploration blockbuster has been building for months and now, after reactions from numerous preview screenings began leaking out, things are reaching fever pitch.

McConaughey himself talked up the movie at the Los Angeles premiere, saying on the red-carpet: "It's wilder than any other ride I've seen on film and that's what it is, it's a hell of a ride."

"It's got a lot of values that people will take away from it and it's going to be very personal to anyone who watches it at the same time. Everybody I've talked to - and I've talked to hundreds - take something different from it that sticks in their craw for days afterwards. So I'm looking forward to seeing it myself for the second time to see what I come away with tomorrow."

Interstellar follows a group of explorers making use of a newly discovered wormhole to surpass the limitations of human space travel. Oscar-winner Anne Hathaway plays another of the explorers - Brand - and she used similar imagery to talk up the film.

"It's a ride you want to take, I'll say that much!" she said at the premiere.

"I'm just really happy for Chris (Nolan) and Emma (Thompson), I think they've put something really special out into the world and everyone seems to love it. I'm really proud to be part of that," she added.

Interestingly, reactions to Interstellar have been mixed. Some have heralded it as a genuine masterpiece - Nolan's best work to date - though others have waved it away as nothing but a nice looking science report.

"The story is ever-ambitious, sometimes riveting and thought-provoking, but also plodding and hokey and not as visionary as its cutting-edge special effects," wrote Claudia Puig of USA Today.

"What pulls you in is its hugely confident architecture as a piece of storytelling - its brave fictitiousness. Nolan comes very close here, one might almost say agonisingly close, to forging his masterpiece," countered Tim Robey of the Telegraph.

Interstellar hits theaters - including IMAX - on November 7, 2014.
