I'd like some feedback about the following sitcom pilot idea, which I hope could work as a series for BBC Radio 7's "7th Dimension" slot, which broadcasts sci-fi shows, including some comedies.
Doors is a sitcom about four people who travel across various dimensions. Each episode would take place in a different dimension, meaning you can have an almost infinite range of ideas. One episode could be set in a dimension in which Hitler won the war. The next could be one where the world is one massive reality TV show.
Each of the dimensions is linked by a single, ordinary looking wooden door with a brass knob in the middle of it. The doors lead to "The Corridor", a infinite space with an infinite amount of doors leading to an infinite number of dimensions.
The four main characters each come from an alternative dimension, none of which is ours. The main character, Professor Rebecca N. Jacqueline, is a botanist who comes from a dimension which is vastly different geologically. In her dimension, gold and diamonds are in abundance while other materials such as aluminium or iron are rare and thus of great value. Most people in Rebecca's dimension live underground and so she is one of the few people who regularly visits the surface.
While outside, Rebecca discovers her dimension's door to The Corridor. While looking around and examing what is behind the other doors, she encounters the second of the main characters - Sir Rover of Goldfields.
Sir Rover is a dog-like creature who was a soldier in his dimension. During his time in the army, he was injured in various ways resulting in having several artifical body parts including a gun for a paw. However, nearly all of his body parts are steam powered. As a result, he feeds on a diet of coal, resulting in steam and smoke bodily emissions. Despite this range of differences, the main defining factor in Sir Rover's dimension is that water is coloured indigo.
He is in The Corridor because he deserted from the army - which is punishable by death. He is now highly suspicious of everyone he meets for fear they might be spies from his dimension. Once he believes Rebecca that she is safe, Sir Rover takes him to see the man he most trusts, who is the show's third main character: Shinji Sasahara.
In Shinji's dimension, people have vastly superior eyesight. Shinji therefore wears special glasses as his eyes look different to those of most people and he does not want to put people off him. However, his entire dress-scene and behaviour is questionable: he is very flamboyant and is described by Rebecca as looking, "like a gay pimp". Shinji works as a surveyor for the Corridor Council, an organisation dedicated to cataloging all of The Corridor's dimensions. He is very proud of his work and finds almost anything interesting. However, his curiosity can be his downfall.
Shinji explains to Rebecca everything about Corridor: how it came into existance, the importance of dimension's helping each other and being careful to make sure to protect people from dangerous dimension's. Shinji offers Rebecca the oppotunity to work alongside him and Sir Rover in helping fill up the catalogue, an offer she accepts. Shinji therefore suggests that she should hook-up with a friend of his in order to help. This friend, the last of the main characters, is Knicki.
Knicki, or to give her her full name, Mistress Knickers Crack, is a half-cat/half-woman from a dimension which is pornocratic - everything in her dimension is sexual to the point that not mating is a crime. Knicki is friends with Shinji because her dimension is technology advanced. She claims to work as a guitarist, but it is in fact a cover. She is actually a spy working for her government, which unbeknown to her "friends" is planning on invading and conquering all the others. Knicki sees Rebecca's world as a good target because of the amount of wealth on it.
While the pilot would introduce the audience to the world of Doors, episodes in the series would involve the quartet traveling to various other dimensions, with each character with their own objective. Shinji to explore and learn more, Rover to protect himself, Knicki to provide information for her bosses, and Rebecca just for the fun of it.
