A recent conversation with friends about how much it costs to go to the cinema – €15 that afternoon and the sun splitting the sky – coincided with a watch at home of Fountain of Youth, a globetrotting Apple TV+ family adventure where, it seems, money was no object.

Whether director Guy Ritchie’s latest would hit paydirt if it was big screen-bound and up against Mission: Impossible – The Final Reckoning is another matter, but it will fill a couch afternoon at home, especially if/when the weather turns.

Watch: Eiza González and Domhnall Gleeson discuss making Fountain of Youth

John Krasinski and Natalie Portman play adventurer Luke and art historian Charlotte, estranged siblings who reunite to find “the most important archaeological discovery in history”. Domhnall Gleeson is the Irish billionaire – no messing – bankrolling the search and Eiza González is the mysterious agent out to stop them.

This “one story, five continents” caper opens with a set piece containing all the chutzpah that Ritchie is famous for and which suggests that the seat-of-the-pants shenanigans to come will be no hardship. Fountain of Youth has its moments, but the dreaded Exposition Truck also backs up to get in the way of the fun – so much so that in one dialogue-dump of a scene a character actually says, ‘Ok, go on…’. The background plot is way too complex for what the movie is meant to be; a bit of Treasure of the Sierra Madre-style moralising without all the BBC Two, 9pm would have been grand.

Fountain of Youth wants so badly to deliver all the Raiders of the Lost Ark feels that it even calls Luke and Charlotte’s late father Harrison. Ah here, the freewheeling energy and chiselled charm of Spielberg’s 1981 classic are untouchable. It’s a film that never gets old. If you want to be 10 again, you know exactly where to go.
