There are two scenes, one will be with the use of a green screen. We have an actor standing still in front of a green screen, facing away from the camera. He will be facing a window showing a space battle above Earth.
The second scene is outside of the ship, overlooking the battle. A wormhole opens up and the ships pile through, destroying the fleet surrounding Earth.
These are video, not still images and must be very realistic.
Please include previous examples of work, preferably space based.
