Undoubtedly one of the highlights of this year’s festival, Gerry Flannagan and Rick Zoltowski make a charming, funny clown duo, as they attempt to explain in ‘visual’ terms, Stephen Hawking's brain boggling book A Brief History of Time. The two men transform themselves into ‘negatively’ and ‘positively’ charged particles, a two-headed scientist-cum-monster (with expert improvising on questions thrown from the audience) and land a space rocket on a planet (actually, Flannagan's bald head). This show is fresh, lively energetic and very very funny. With Zoltowski as the ‘straight man’, Commotion are somewhat reminiscent of Morecambe and Wise. Today Battersea Arts Centre – tomorrow the South Bank?
