Not sure about wholesome "Christian" movies - not sure what you mean by that.

Father Goose was a good family flick. Operation Petticoat was innocent fun. Most John Wayne movies (although those movies might be a little rough for young kids). So many more, but you should look around for movies released in the 1950s/early 1960s.

Maybe Ben Hur might fit the bill for you. Or, The Sound of Music. They both have religious Christian themes in the background.

Older Mel Gibson Movies seem to be a decent choice:

The Patriot - A reluctant combatant in the War for Independence who changes his mind after his family is attacked needlessly by the redcoats.

The Passion of the Christ - Mel’s film about the crucifixion.

Conspiracy Theory - A mumbling, leaflet printing cab driver seems schizo, but is he crazy, or is he on the cusp of uncovering something?

The Road Warrior - The Mad Max movie that was full of awesome stunts and a solid story

Apocalypto - Gibson’s film about the demonic powers that be and their bloodlust as they sacrifice the weak and innocent to entrench their illusion of power. Pretty much an allegory of the jews.

Braveheart - Scot William Wallace stands up to the faggotry of England’s drive for power and debauchery.

Hamlet - Mel portrays the Danish Prince who pursues revenge against his uncle.

Donovan's Reef is pretty good.

I like the 'A Thief in the Night' film series. I'm not pre-tribulation myself (I don't know, really) but I like those movies ; it's about the journey of people left behind after the rapture. It's old and slow, like they used to make them.
