Director Guy Ritchie keeps the treasure hunting at a nimble pace even if John Krasinski and Natalie Portman fail to boost the charm of a pair of bickering siblings.

Guy Ritchie's recent, prolific output has been a bit like bombast-lite Jerry Bruckheimer, and Fountain Of Youth gets closer than ever.

"Fountain of Youth" - the latest swashbuckling adventure following a search for a mythical location - has finally dropped. The Guy Ritchie-directed film stars John Krasinski and Natalie Portman as two estranged siblings who get roped into hunting for the titular Fountain of Youth while others aim at keeping the location a secret.
