She would have been too young to play her.
absoulutely not! Danni Minogue is only 2 years younger than Emily Symons, Danni was born in 1971 and emily in 1969 - that is certainly not a big age difference! The old fashioned clothes and horrible hairstyle make Marilyn looks older.... So with a wig and terrible clothes and awful make up, danni M would have looked just as old...
Well, not quite because Danni Minogue still has her face pumped full of botox, her lips full of cow's butt and whatever else she's had done, so she'd look rather odd as 2010 Marilyn. But true, if you Google pictures of Emily when she was in the UK not long ago, she looks younger and far less nanna. ;)
