New Zealand's Rhys Darby has been threatening to devise a set to match his physical comedy talents, and he finally delivers with Jekyll and Hyde 2030.
This futuristic reworking of Robert Louis Stevenson's chiller with a spaced-out nod to Alien is the perfect showcase for the most enjoyably rubbery face since the young Rowan Atkinson.
With just a stool for a prop, the fairhaired Kiwi breathlessly portrays the doddery scientist who takes a youth elixir to join a mission to Mars. Jekyll becomes a square-jawed hunk, but then mutates into a bug-eyed behemoth and runs amok. There is no hiding behind desks, Darby morphs before our eyes.
As well as providing full supporting cast and pulling enough faces to entertain an entire nursery, he also has an impressive artillery of sound effects. Electronic doors whizz, walkie talkies buzz and helicopters sound as if they are landing on the theatre roof.
Slapstick and sharp, culture-spoofing gags complete the picture.
The closest comparison is not in comedy or physical theatre but in music. Darby does for humour what one-man orchestra Bobby McFerrin did for pop. He may be a novelty act, but he is a brilliantly beguiling one.
Rhys Darby is at the Pleasance Theatre until 30 August. Information: 0131 556 6550.
