If hollywood producers are so famously picky, I wonder if they will reject a script with this font because it simply looks different.

I don't think you'll be able to explain to them that it is metrically identical, just like you can't explain to your garbage man that you are using a decomposable plastic bag, but they have the strict order to not accept plastic in your organic trash (if you live in the kind of place that separates trash like this).

It could be great after you get your screenplay accepted, if you want to have a nicer copy that matches line-by-line the courier version.
