By casting Emily Blunt and Dwayne Johnson, two actors of rare personal charm, this Disney adventure should have managed to transcend its somewhat unpromising origins (it was, like Pirates of the Caribbean, based on a theme park ride). But for some reason, while both are perfectly likable independently (Blunt in particular is a feisty joy as scientist Lily Houghton), they fail to gel on screen.

Their lack of chemistry is not fatal to the film – director Jaume Collet-Serra creates a romp of a picture booby-trapped with adventure movie tropes (arcane curses, snakes, evil Germans) which, while they might seem familiar to Indiana Jones fans, still combine to make for a decent family flick. It’s just that a movie that requires its characters to “mend a broken heart” as part of an ancient riddle should probably have a heart to begin with.
