Handing over AE projects....?

Hi there

I have been working with a production company creating a huge animated sequence for them. I am supposed to be delivering a single movie at the end for them to use. I have had an email from the director now requesting all my source files - by which I think he means project files.

This is outside of my comfort zone. This wasn't agreed and I don't like to hand all this stuff over - all my working knowledge from 9 years designing, animating and using the software. Why? Well I am aware that there is a junior at the company who uses After Effects. I have a well founded fear that they will not ask my in to do all the changes on the project and cut me out of the picture.

So moral dilemma time. Do I just roll over and hand over these (in the interest of keeping the client sweet), or do I doggedly hang on or do I offer to sell them.....?

I do not want to seem like some kind of prima donna - but at the same time I don't want to hand over the Colonel's Secret recipes!

Your thoughts clever Cows please....
