Eevil scientist John Glover ( Brimstone, Smallville ) is after them.
This is a mediocre made-for-TV pseudo-thriller.
A sentient lion and his circus buddy [Dom Deluise - Stargate SG-1 ] take balloon ride, and end up in the land of oz. The wicked witch kidnaps the fat human, and forces the lion to go on a quest. On his way he meets assorted buddies, sings songs and so on.
Derivative crap, but child-friendly.
Casper's enemies are the Hellfire Council, led by Malcolm McDowell ( Clockwork Orange, Star Trek: Generations, Tank Girl ). They are the richest and most powerful men in the world, who want to rule by Black Magic instead of economic power. Fools!
Casper prances around dressed as Indiana Jones . Luckily, the French Foreign Legion have a unit in British territory, about a thousand miles from where they should be. They play an important part in his plans.
Casper teams up with a beautiful Egyptologist, just like in The Mummy . She opposes the shipment of artefacts to the British Museum. Of course, Casper would rather claim them for the American Empire's Smithsonian. Or perhaps he would give priceless pre-Islamic relics to anti-American locals?
It turns out that the discovery of Tutenkamun's tomb, in reality performed by Howard Carter and Lord Caernarvon, was somehow achieved by a Yank and a gaggle of mercenaries in the pay of France.
This sad piece of crap was directed by Russell Mulcahy . My, how the mighty have fallen - he started with Highlander , then fell to Blue Ice, but he must be desperate to pay the bills now!
Strangely, the writer was also responsible for the similar, yet far superior Librarian: Quest for the Spear . Seems he was a one-hit-wonder too. Poor bastard. It's downhill from here for him.
The second half is full of crap as well. According to this, Egypt was now somehow a Republic in the 1920s!
