I saw it three or four days after it opened. I thought, "That's a cool poster" and didn't know anything else. Saw it in a mostly deserted theater with a housemate. That first scene of the Star Destroyer chasing the cruiser is embedded into my consciousness.

I saw it again a week later in a much better setting: The Coronet theater in San Francisco. The theater was packed, pot smoke filling the air, the audience booing Darth Vader. That is also a wonderful memory.
