Harry Potter and The King's Speech star Timothy Spall had to be rescued by a lifeboat this week when he and his film crew got lost at sea.
The actor - who plays Peter Pettigrew in the Harry Potter films - is sailing round the British coast in the Princess Matilda barge for a BBC series Back at Sea.
But he called for help on Wednesday at 9.40pm when he and his four-strong film crew lost their way.
An RNLI rescuer got on board to help them after the Sheerness lifeboat crew tracked them down off Stangate Creek in the River Medway estuary.
According to The Sun, their 55ft Dutch barge was then escorted to safety at the Queenborough Harbour on the Isle of Sheppey.
Spall, who lives in London with his wife Shane, reportedly taught himself how to sail by reading children's books.
Perhaps he should invest in a proper 'man manual' next time? Just a thought!
