Stargate: Horizon is a virtual series created by Alex Rubit.
Basically what that means is, it is a series that's conceived just like a one hour television show, written in script format. In short, it's just like a weekly television show, the only difference is that you read the episodes rather than watch them on TV. But in terms of characters and storylines it's just like a TV show. The show is even made up of seasons, with its four season about to come to an end, and it originally premiered on November 4, 2004.
Some frequently asked questions include: why do you have a cast if the series isn't being shot?
Well, basically as I just mentioned, the series is conveived just like a television show. That means that we write the characters with the voices of specific actors in mind, and... there you go. So are these actors in any way involved with the show? Not really. But they do make a pretty good fit for the characters.
How does SGH fit in with the Stargate television shows (SG1, Atlantis, and Universe)?
Stargate: Horizon is a series that takes place in the Stargate universe, but it is an original series. We do not rely on plotlines established in the television shows, but much rather have created our own corner in the Stargate universe, so to speak.
Do I have to be familiar with the other Stargate shows to be able to follow this one?
No. In a word, no.
The show is written in script format. Will that be challenging to read?
Not really. Reading scripts is very easy actually. It tells you essentially just what you'd see on the screen.
So I'm new to the show. Should I start with Season One?
That's up to you, of course, but it's not neccessary. The series has improved greatly since the early days, and frankly, the early episodes in no way reflect the quality of the series as it is today. Not in the least, actually. So if you want to catch up from the first episode on, you can do that, of course. But should you choose to start with episode one of Season Four (or Seasons Three or Two for that matter), you would still be able to know exactly what's going on.
