MAMMA MIA! stars Julie Walters and Meryl Streep had fun onset - at the expense of their co-star Pierce Brosnan.
The actresses would team up to pull pranks on the former Bond star, because they knew he was not confident about his dance scenes.
Walters says, "Pierce was really nervous when he came in and he was the last to join us for dance rehearsals.
"So we played a joke on him. We'd already had quite a bit of rehearsal for one of the routines - Voulez Vous - and it was quite complicated.
"When he arrived we said to him 'Oh no! We haven't rehearsed at all' - but of course we all knew the routine perfectly.
"So he tried it - and thought he was a total klutz compared to the rest of us. We did let on eventually though."
