Hollywood stars Selma Blair and Molly Shannon have given Australian cult comedy Kath & Kim an American make-over.

The actress' were spotted filming scenes for the show in Los Angeles ahead of its US debut on October 9.

Instead of Fountain Lakes, the American version sets the mother daughter duo in the suburban sprawl of Phoenix, Arizona.

The original version, which Jane Turner and Gina Riley both created and starred in, quickly won a loyal following in Australia and abroad,and even featured a guest appearance by Kylie Minogue.

It remains to be seen if the unique brand of comedy will translate for an American audience, and so far responses to a big budget advertising campaign have been lukewarm.

Shannon, 43, stepped into the role as Kath while Blair, just seven years her junior, plays gobby daughter Kim.

Foxy moron: Selma says she gained more than a stone for the role

Blair gained more than a stone for the role and completely transformed her usually sleek look.

She says: 'I wear rhinestones on my nails. This is a new thing for me because I have to wear these nails in real life so I am always apologising for them.'

'Then I realise I am apologising to people who have these nails, so I am insulting people every day.

'It's been really, really strange wearing this wardrobe around.

'It's been fascinating asking, "What does an American girl think makes her really pretty?" They think it's pretty to have extensions, even if people know they're extensions.

'It just looks so fake and ugly, but it's like a status symbol.'

The tone of the show will be less slapstick than the original, according to executive producer Michelle Nader.

She says: 'This will have more of an emotional underpinning.'
