Actress Emily Mortimer is still haunted by the lurid birthday card she gave to moviemaker Martin Scorsese.
The Shutter Island star was shooting upcoming film Hugo Cabret on location with the director when she learned it was his birthday - and realised she had no gift for him.
Desperate, she remembered she had a birthday card intended for her godson in her luggage - and she decided to give him that.
The card in question featured a photo of British comedienne Catherine Tate's seedy pensioner character Nan on the front with a spoken-word message inside.
Mortimer recalls, "I thought, 'That is the most brilliant thing...' (Tate) is brilliant but she dresses up as this horrible, wee-stained old lady with her knickers round her ankles.
"It was five o'clock in the morning and we were about to start the day, and I thought. 'This is the most brilliant thing; I'm gonna give him this and it'll be better than all those expensive presents because he'll see the charm of the British sense of humour.
"It was a disaster... On the way in (to work) I was saying to (co-star) Sacha Baron-Cohen, 'Do you think this is a good thing?' And he was a bit like, 'No, I don't think you should.' I was thinking he was jealous.
"But, as he (Scorsese) opened it I could see his little face fall... He's actually a very classy guy and very refined... and this old granny with wee on her knickers... I could see him trying to be nice but it was just awful, and I couldn't look him in the eye ever again.
"Sacha loved it - he tormented me the whole of the rest of the film."
