Movies like Indiana Jones / National Treasure?

I've already seen:

indiana jones (i think almost all parts)

national treasure 1 & 2

journey to the mysterious island

I'm basically looking for films in which researchers discover graves or rediscover lost cities.

I have just played through the uncharted series (1-4) for the PlayStation for the second time if that also tells who what…

The film shouldn't be older than 2000.

Quatermain with Richard Chemberlain

or

Michael Douglas and the adventure "In the hunt for the green diamond"

do not meet your claim before the year 2000.
