The ruggedly handsome Jersey-born actor will slip into Superman's distinctive blue and red spandex for Man Of Steel.
Cavill affirmed his action man credentials as Perseus in yesteryear swords and sandals romp Immortals - a triumph of brawn over brains that played up his impressive physique over the paucity of heartfelt emotion.
That woodenness in front of the camera is glaringly apparent in this pedestrian spy thriller that casts itself in the mould of The Bourne Identity but falls pitifully short on every count.
As the accidental hero at the centre of a deadly conspiracy, Cavill lumbers just like the film.
In sequences that call for him to run for his life, he lollops in an awkward fashion then delivers pivotal lines without any trace of feeling. Like a block of chiseled marble, he's beautiful yet stone cold.
Business consultant Will Shaw (Cavill) joins his father Martin (Bruce Willis), mother Laurie (Caroline Goodall), younger brother Josh (Rafi Gavron) and his girlfriend Dara (Emma Hamilton) on board the family yacht in Spain the same week that his company is threatened with bankruptcy.
The timing of the holiday couldn't be worse and Will's Blackberry continually trills and buzzes to the obvious irritation of Martin, who eventually throws the device overboard.
Will is apoplectic - as much as Cavill can convey - and swims ashore to buy a new phone. When he returns, Will discovers his loved ones have been abducted.
A plea for help to local police exposes a dark family connection to feisty CIA agent Jean Carrack (Sigourney Weaver) and her henchman Gorman (Joseph Mawle). With less than 24 hours to rescue his family, Will places his trust in a stranger called Lucia (Veronica Echegui) to guide him through Madrid's teeming streets.
The film is an interminable bore, lacking suspense, solid performances or a coherent plot.
Continuity errors abound - Will's swim bag has miraculous vanishing powers - and every role is woefully undernourished.
Even car chases appear to be conducted within European speed limits.
"I'm getting sick of this!" growls Weaver's character halfway through. We echo her sentiments between yawns.
