Lucy Lawless performing live at Universal Citywalk at Universal studios, Los Angeles, California - 28.06.08

The New Zealander , 40, is back on TV as a madam in an upcoming episode of CSI: Miami, but it's another global hit she craves for - and a return to the fantasy series which made her a nerd pin-up.

She says, "It'll have to happen fairly soon. If it takes much longer, they'll cast some 20 year old in the role and ask me to play the mother. I'd tell them to go to hell, or worse - I'd do it."
