Australia's Kath and Kim successfully transitioned to UK TV and probably a large number of other countries.  In the US, however, they prefer their sitcoms home grown.  So in October NBC launches the US version called:  Kath and Kim (unsurprisingly).  You can check out the previews here.  Not much to go on but one of the great stars of the original was the shopping centre butcher and aging lothario Kel Night and he does not appear to survive the transition at all well and Sharon does not survive at all.  Magda Szubanski refused to let her character cross the Pacific and is replaced by a gay male.
