One of my most favorite movies is The Last Starfighter, a sci-fi flick where a young man plays a video game machine which is actually a training console for an advanced starfighter. Aliens who own the game find him, pick him up, and get him to pilot a really powerful space ship, a model of which is pictured below.
It's one of those designs that use the X-type planform, similar to the X-wing fighter from Star Wars, the X-Bomber from Star Fleet, the Hawkwind from Air Raiders, and more.
It not only remains one of the coolest ships ever (because of it's power), but the movie's story is great.
Oh, did I say the Gunstar has a wedge-shaped front? LOL
