No offence, but I don't quite like the idea, here. The story has been used before (Egyptian Holiday) and will probably be used again (The Pharoh's Quest) in the future (Although this doesn't seem like it's based in Egypt, it still seems like an un-original story). Also, the characters are quite cliche (A treasure hunter- I assume young in age; and an old Doctor), I would come up with some dashing characters, some who portray more feeling and new emotions. Also, even though you say that the film will have 'awesome pan and dolly shots', people still won't be interested unless you have good animation, so you should make a couple of tests to see how good your pans and dollys are.
