Stargate: 10 Behind The Scenes Secrets You Never Knew About Children Of The Gods
4. The Production Team Ran Out Of Money So We Only Got Half Of A Kawoosh
If one watches Children Of The Gods before the original film, one will notice a drastic difference between the two Gates. This is not simply the design of the final lock for the seventh Chevron, which is open in the film while being identical to all of the others in the series. The actual Stargate vortex itself is missing an additional element in the series.
In the film, once the gate address is locked in and the wormhole opens, the 'kawoosh' that is seen extends out by several feet, before retracting into the event horizon - and continuing out the back, forming a whirling funnel. In the series, the sequence is almost the same, though the funnel is now missing from the wormhole.
The reason behind this is frustratingly simple - they ran out of money. The design of the gate opening was created by firing an air cannon into a pool of water, though recreating the funnel proved to be too costly at the time. Therefore, there is now only one appearance of this element in the franchise, that being the original film.
Added to this, the extra-long visual effects sequence from the film was abandoned, though it made another appearance in 'The Fifth Race', used as a handy way of showing that O'Neill was hopping galaxies. But that is another list altogether.
