I think there was even a nod to three amigos with this line:
"As long as there is injustice, whenever a Targathian baby cries out, wherever a distress signal sounds among the stars, we'll be there."
I guess they're both sort of references to Tom Joad's famous speech in The Grapes of Wrath though.

Add
Tropic Thunder
to the list of films with a similar theme where actors are put into a situation to play out their characters because someone thinks their characters are real.

I've been shot already!
I've seen things that would make you want to write a book on how to puke.

Good night Ned

Sort-of.
They do have similar set-ups, but
Three Amigos
and
Galaxy Quest
are very different beasts.
And I do honestly believe that
Galaxy Quest
is a much stronger film that holds up a lot more, especially on repeated viewings over time. It's one of those movies It's been out 17 years, and I've watched it at least a few times every single year since it's come out. It never stops entertaining and never stops charming you, and you never stop loving it, no matter how many times you see it.
And FURTHERMORE, this is my signature! SERIOUSLY! Did you think I was still talking about my point?

You did it incorrectly. It's supposed to be: IN SPACE!!!!!!!!!!

The big difference being this movie is funny.
Not when that loser Tim Allen is in it.

Three Amigos is hilarious!
"You keep him in here, and make sure HE doesn't leave!"

Just saw G.Q. and enjoyed it quite a bit. Three Amigos I LOVED when I was a kid, but I saw it a few years ago and was disappointed. I'll try again one dayit did have its moments.

Martin Short emptying half a canteen of dirt into his mouth. Still makes me giggle like a kid.
then whoa, differences

Three Amigos had its moments.

Could it be because I am turning 70 in March? Nah. Could it be because Raquel Welch chooses to sleep in her condo instead of weeth me? Mm.

Forgive me, El arbilab. I know that I, Zero_Wolf, do not have your superior intellect and education. But could it be that once again, you are angry at something else, and are looking to take it out on me?

Death is the road to awe.

Never saw it. But I would hate to think a person would tell me I had a plethora and find out that person had no idea what it means to have a plethora.

Shut your mouth!!
Three Amigos!
is a timeless classic!

The big difference being this movie is funny. Three Amigos wasn't.

In my experience a LOT of Trek fans will rank Galaxy Quest near the top when listing their favorite Star Trek movies.
Philo's Law: To learn from your mistakes, you have to realize you're making mistakes.

I'm not dizzing Save the Whales - but its better than that, too.
A gentleman will not insult me, and no man not a gentleman can insult me.

Now that you mention it.
It's also a better Star Trek than any of the theatricals except maybe Save the Whales.
