Stargate (1994)

Plot:

A stargate found in Egypt in the 40's is put into storage until a genius figures out how to operate it. Now, there is a link between earth and an unknown galaxy millions of light years away. Colonel Jonathan 'Jack' O'Neil is sent with some men to explore the unkown but there's only one problem: When they reach this earth-like planet, there is no way to re-open the stargate without the right equipment. They must fight off evil and all to get the stargate back into its "locked" position and save the earth from the deadly bomb which is going to be sent through the stargate by the evil leader...
