I am trying to ID a film. Very probably a TV movie. US made, live action, seen on British TV late 80s early 90s and almost certainly, from the hair styles I recall, made in the 80s. Most likely broadcast on Channel 4.
No actors that I can identify leading me to think it's pretty low budget.
Specifically remember a line of dialogue like "more bombs for new London" as spacecraft depart the moon on a mission. The name of the city may easily be misremembered. Could just as easily be New Washington or New... something.
SFX was all physical models. No CGI. The aesthetic was Star Wars/ Original Battlestar Galactica, so very gray looking ship with lots of hatches, pipework and vents like the surface of a Star Destroyer.
I don't recall flight helmets or details of the pilot's uniform. I do recall that the ship was not a fighter and may even be a civilian ship.
Very uncertain on the plot but seemed to be earth being threatened and attacked by an evil overlord from his secret base on another planet. The line of dialogue I recall was spoken by the pilot of a spaceship leaving the moon. The mission was to infiltrate the planet/base where the bombs directed towards earth were being launched from.
I may be conflating two separate films but I think there was a scene later on, as they key character (and possibly the female love interest - there always is one of these things) approached the enemy base across a wide grassy expanse of land and the main villain appeared as a giant rotating hologram in the sky to give a sort of "nothing can stop my evil pan from succeeding" type speech.
Beyond that I really don't recall any more except that it was a small cast of central characters.
