Thanks to @stevebunce for his Tweet that alerted me to this.
Looks a great film. My boys are definitely interested.
I like this version of the trailer as it has the Spanish sound but also English subtitles.

But it also exists without the subtitles.

And I quite like the English version which is completely different.
