Trying to find the name of an old black and white movie where a man and woman end up on an alien spaceship. The ship is full of cubes with kind of a horn out of the top. They plug caps into the cubes to learn how to operate and defend the space ship from an alien race. They fire missiles from a flimsy looking space ring at the alien space ships. At the end I remember them being transported back to earth. I can't seem to find anyone else who remembers this movie.
Your description reminds me of "The Terrornauts", a 1967 movie based on the novel "The Wailing Asteroid", by Murray Leinster. The story involves a group of characters who receive a radio signal from space. After they respond to the call, an alien ship appears and transports them to a deserted space station, where they are required as crew to repel an invasion by a different, hostile alien race.
This Island Earth (1955)
I don't remember the control cubes and can't find any pictures of them, but everything else fits with this classic movie:
- From the 1950s (though not black & white)
- A man and a woman are taken aboard an alien spaceship
- The spaceship fires missiles at alien spaceships
- After the battle, the man and woman are brought back to the Earth
In the images below, one of the spaceship's crew does wear a cap, though I can't tell if it is used to control the ship or missiles.
