The former stars of a Star Trek-like TV show are mistaken for genuine space heroes by an alien race searching for saviours. Three Amigos! / A Bug’s Life redux, perhaps, but with excellent casting, a sense of fun, and affection for genre and conventions (of both kinds) throughout.
Harry and friends search for a hidden part of Hogwarts. Second and perhaps the least of the Rowling adaptations, this mimics the structure of the first, though adds enough novelty to please fans, and begins to develop the series mythology.
An orphan boy finds that he’s a famous wizard child; his education begins. The first Potter movie is a straightforward breeze through the book. Awkward early performances and under-par CG aside, this is reasonable family fun, though no classic.
Decent-enough adaptation of the Douglas Adams radio series/book/TV show which suffers – inevitably – from over-familiar source material; the new stuff works best. The cast works hard, production design is great, and there’s a sense of affection for the material and Adams throughout.
