Tara Fitzgerald?
She gets tickled a lot less than Portia DeRossi (before she had the American accent)
There's an erotic tickling theme running through much of this movie, with about...3 or four scenes of note. From memory, when they go swimming and they tickle attack the 'Giddy' character, when they're lying down at the 'picnic' (mainly discussing what they would do to her later), when they're at the river again (more erotic..."I know somewhere where she'd be REALLY ticklish..") and then the very brief scene where Elle McPherson asks Tara Fitzgerald if she's ticklish when they tie her to the tree, and then goes for her.
It's definitely worth watching and capping if you haven't seen it before.
Possibly the best mainstream tickle movie I've ever seen, and very attractive ticklees and ticklers too.
And it's predominantly Australian, and to do with the artist Norman Lindsey - who is quite interesting in his own right.
So you should watch, tape, cap it if you get the chance.
How's that for a recommendation?
