Project over runs by 75% ... how do I charge 75% more..

I posted the question about project file handover - but now the tale has taken another twist...


First up the AE project dilemma hurdle has been crossed I didn't give them the project files and they accepted that.

Here's problemo number two.

At the beginning of the project I had to quote for a two minute film. The script was never two minutes despite the director saying he would get around to editing shorter it always read at 3.30 I was told to continue with a story board which in order to get every image to read on the time line ended up being 3.30 All the way along the director said I know this is the wrong way to work - but I want to put the voice to your picture.

No I have purchase order* on with a 2 minute duration.

They have made a 3.5 minute film which they expressly asked me to make.

Now I have to deliver so I say I want to have a written promise that they will undertake to pay for the additional work.

The director is saying well the CEO is paying for it and the budget was set at..X and I am saying well I need X plus 75% for the additional time taken to create the additional minutes. The director is saying I will get you more money ..... wait for it .... on the next project.

Using your combined wisdom and tact and considerable wit - how do I tackle this one - bearing in mind I am supposed to be delivering the finished movie tomorrow.
