If a child just turned up on your doorstep, would you keep him, or would you phone child services? While 99.9% of the population would do the latter, Jennifer Garner and Joel Edgerton just decide to keep him, believing he's the embodiment of a wish they made to have a child. Presumably their right, as this is a Disney movie and not some hard-hitting tale about weird, delusional parents. Now a new trailer for the film has arrived. It's out in the US in August, but no UK date is set yet.
