Journalist reviews of the upcoming sci-fi action project from director Guillermo del Toro are currently embargoed, but West and others have given their thoughts after preview screenings.
West tweeted that the film is one of his "favourite" movies ever, praising del Toro for producing such a spectacle.
I saw a pre-screening of Pacific Rim yesterday and it's easily one of my favourite movies of all time.— KANYE WEST (@kanyewest) July 4, 2013
He added: "This is not another "Robot" movie. Guillermo del Toro is a master."
Emma Watson also tweeted about the film, saying: "Guillermo's new film is out soon. Beautiful special effects, huge scope, BIG battles. Wish I could fight like Mako."
Hip-hop producer RZA also praised the movie, writing: "#PacificRim was good yo. Visually it was Astonishing. Sonic was Bionic and action was imaginative. My son says "it was Awesome...""
Pacific Rim is set in a future where mankind is challenged by monsters called Jaegers that have risen from the ocean.
The fate of mankind lies with an old Jaeger piloted by a washed up veteran (Charlie Hunnam) and an unproven rookie (Rinko Kikuchi).
Idris Elba, Ron Perlman, Charlie Day, Robert Kazinsky, Max Martini, Clifton Collins Jr, Burn Gorman, Larry Joe Campbell, Brad William Henke and Diego Klattenhoff will also feature in the movie.
Pacific Rim will open in 3D, IMAX 3D and 2D cinemas on July 12.
