Movie-obsessed madness

How do you drag mime into the 21st century, ponders Dave Umbilical. Then it hits him: 'You add sound!' Genius.

But don't let the m-word put you off. With Thwak you get more than an hour of movieobsessed madness that shows what fun two guys can whip up mucking around with a mic.

Like all good comedy duos, there's love and hate in Dave and Shane's relationship. Their power struggle is played out in mic-busting sound FX battles that fast-forward through kung fu and Wild West shoot-outs with glee.

If that sounds too laddy - and it is a boy show - then what lifts it is the mix of Shane's sarky edge and Dave's wide-eyed wonder, which undercuts any hint of Aussie machismo. A night that could just give clowns a good name.
