Added onto this the score comes courtesy of Ramin Djawadi who's masterful use of themes on Game of Thrones is carried over to this film for some great emotional cues and many a rad motif courtesy of Tom Morello on guitar. The cast is essentially a rogues gallery of TV's better dramas playing variations on roles they've nailed in the past (see: Elba, Hunnam and Klattenhoff) and some inspired casting of It's Always Sunny's Charlie Day who, as should be expected provides some effective comedic relief. Maybe it was the incredible effects shots of robot related destruction used as a throwaway shots, but what I think really sold the opening sequence and the film as a whole is the enthusiasm Del Toro clearly has for the story he's telling. entering the cinema from a world where these events rarely occur is initially a lot to throw at the audience, but it's handled so effectively and without tongue in cheek that it quickly becomes a world I had a blast experiencing. This opening does a great job in conveying the scope of a film which is big, not just regular big, but like, Jason Biggs in 1999 bigg.

Within the opening 15 or so minutes Charlie Hunnam's voice-over establishes the reality of a future where monsters (the Kaiju) repeatedly invade earth, to stem this humans have created giant robots (Jaegers) to combat them in increasingly badass iterations.
