Möglich means 'possible' in German.  Take that to mean what you will. As a title, it's quite random, imaginative, unusual - everything in essence that this show is. Although we meet many different characters, we find one man on stage; and that man, at time of first meeting, has his head in a bucket. Nothing particularly remarkable about that level of absurdity in a Fringe setting. But all is not what it seems, and nothing in this piece is predictable.

The man in question is Douglas Walker, also a member of the improv troupe Racing Minds, and he proves a very talented comic actor. Walker describes comedy as an art form, and there is indeed creative elegance blended with purposeful clumsiness in his work. Möglich is made up of a number of one-man sketches, using lighting effects, slight costume changes, and various accents and voices to clarify and signify the appearance of each of these creations. From time to time Walker addresses us directly, but the convention is still very theatrical, and it is more the case that he is still playing a role - that of 'himself'.

This piece is a comedy adventure of discovery. The humour is offbeat and Walker remains in left field throughout. It's not the kind of comedy you laugh at constantly - although there is a joyous abundance of laughter at times, the kind of hysteria that holds up proceedings.

But there are also those moments of tension and seriousness, where we are presented with a dark, unpleasant and sad scenario. He has us on tenterhooks as he presents a character describing the experience of torture, or being surrounded by bodies after a mass hit and run.  For moments at a time, it feels like we're in a totally different type of show - until he deftly turns 180 degrees back into comedy, and on to the next scene before we can catch a breath.

There were scenes which I felt would have benefited from being cut down a little, where it seemed the character had lingered longer than was necessary for either humour or effect.  Many of his sketches though, were short and sharp, adding to the wonderfully bewildering style.

I saw this eccentric comedian's final show in Edinburgh, but he'll be heading to the Brighton Comedy Fringe in late September. If you're around then, you can catch Douglas Walker in what is an excellent and enjoyable piece of comic theatre.
