Angelina Jolie has landed roles for all six of her children in 'Cleopatra'.

The actress and her fiancé Brad Pitt have previously said they didn't want their brood - Maddox, 13, Pax, 10, Zahara, nine, Shiloh, eight, and five-year-old twins Vivienne and Knox - to follow them into acting, but it appears they may have changed their mind after they all appeared on set together ready to film.

'Cleopatra' is also rumoured to star Brad Pitt, which would make it the first film he and Angelina had appeared in together since 2005's 'Mr and Mrs Smith', where they first met.

A source told the Daily Mirror newspaper: ''Their whole family life is rooted in films but Brad and Ange didn't want the children to follow in their footsteps. However, acting is in their genes, and it could turn out to be the start of something big for the next generation.''

Vivienne has previously appeared alongside her mother in 'Maleficent', but Angelina said she only let that happen after a long discussion with Brad.

She said: ''I only put Vivienne in the film because the other children her age would be scared of me because I looked quite scary as Maleficent.

''Neither one of us want our children to be actors, Brad and I, but it was just I really couldn't ask another four or five-year-old to do it because kids on set did actually get scared and they would cry when they would see me.''
