Well thanks for that! I have seen it, although I can’t remember where, certainly not in the initial release.
Honestly, I don’t think the “sound and light show” does anything for the film. That little bit of mystery when Dreyfuss walks up into the ship and that’s the last you see of him is a lot more effective, in my opinion anyway.
There’s an old show biz adage, “Always leave them wanting more!” and it’s certainly true. Especially in this case…
“I wonder what’s in there…”
But you know, if the really wanted to have some fun with the audience they could have had Rich walk into that amazing, otherworldly ship and run smack into something like this…
