Angelina Jolie was told off for doing "horrible voices" while recording the 'Kung Fu Panda' sequel.
The 'Salt' actress plays the part of Tigress in the film, but was so concerned about her own voice she began to put on accents – angering the executives behind the film who wanted her to sound natural.
She said: "I've never loved my own voice. Like most people, you hear your own voice and you think, 'Ugh.' So I came in and I was Mae West for a while.
"I was doing southern, I was doing British, I was doing any accent I could come up with. Finally, they had to give me the talking-to that they'd analysed my voice and they'd hired me and they were very fine with my natural voice, 'So please just stop doing those horrible voices."
Jolie is currently working on her directorial debut, set in the Bosnian war, and is also thought to be starring in a new movie about the life of Egyptian queen Cleopatra.
