EDIT: Please disregard this post...

Take a look at this: The Lone Ranger and the Lost City of Gold (1958)

edit: "2000ish" says in the title... sigh, i'm too tired.. anyway.. :-)

That's what I thought but the OP indicates that his father saw the whole movie and to my knowledge no one in history has ever been able to sit through that piece of shit. :P

No, I think watching that movie is probably to blame for ruining your childhood. :P

I presume that it's probably not the 1998 movie "Tarzan and the Lost City", but there's 1999's "The Vivero Letter", which might fit the bill.
There's also an adaptation of H. Rider Haggard's "She" from 2001, but I don't think it had anything to do with gold.

Oh yeah? Now I'm going to regard it even more! Like this: ಠ_ಠ

Saw the thread title and thought of this movie right off. I'm going to second (or is it third, along with gunsynd?) you on this.

Same here. I remember having high hopes for it when it was released and then I saw it... as tinyE noted, ruined childhood.

If it were older then I'd go for The Jewel of the Nile... but that was in 1985

Thats immediately what I thought too

I immediately thought of this movie too (that and its predecessor, King Solomon's Mines) -- what threw me off is that the OP said it was a 2000's-era movie, and both movies were from the mid-1980's (King Solomon's Mines is from 1985, and Lost City of Gold was from 1987). Given that both films were from the Cannon Group, I wouldn't exactly say that they were "good", but they were entertaining and hilarious nevertheless.

Ooh, now I have the urge to go back and watch Invasion USA.

Invasion USA, home of the never ending RPG! :P
I also like the guy getting hit with the rocket at the end and how it doesn't damage the blinds behind him.

Or it could be that the OP just didn't see it until around then. First time I saw The Wizard of Oz as a child, I kind of assumed it was a recent release as well.

What always cracks me up in the trailer is how he uses the single-shot grenade launcher as an automatic weapon in the office building.

Yeah. I was guessing that he was likely referring to the 2004 DVD release, of which I actually wasn't aware. I'm actually considering picking it up now...
