The star is currently in south-east London filming the fourth Pirates Of The Caribbean movie On Stranger Tides and arrived at the Meridian Primary School dressed in full character as Captain Jack Sparrow.
He made the one-off trip after nine-year-old pupil Beatrice Delap wrote to the star asking for help staging a ‘mutiny’ against the teachers.
The school was told just ten minutes before that Depp would be arriving and two blacked-out cars swept through the school gates.
Beatrice revealed what she had written in the letter to the star – or rather his salty seadog alter ego.
She said: ‘Captain Jack Sparrow, At Meridian Primary School, we are a bunch of budding young pirates. Normally we’re a right handful, but we’re having a bit of trouble mutiny-ing against the teachers! We’d love if you could come and help.
‘Beatrice Delap, aged nine, a budding pirate.’
She said that she was then asked by the star to make herself known from the assembled pupils once he arrived, and gave her a cuddle. Beatrice marvelled: ‘He gave me a hug and he said, “Maybe we shouldn’t mutiny today ‘cos there are police outside monitoring me.”‘
Ten minutes warning?!? That’s hardly any time to prepa– oh my God!! He’s Here now!! Hi Johnny, how are you? …. Oh, now he’s jumping out the window. What a weirdo.
