Hi Vincent,
I'm hesitating to answer this question, because chances are that you might not like some parts of what I will be writing. 8-]
One part of the answer is that VSL would have made their instruments sound like EWQL if this is what they were aiming for, really. Obviously they didn't. 😉
Another part of of the answer is that more or less everybody who is into "that Hollywood sound" will tell you that A) it is a moving target and B) it is to be found more in the arrangement of a piece than the "sound". The "trick" here is to write properly and to know what _defines_ the sound you're calling "Hollywood".
That said, of course MIR and MIR Pro are mighty tools to change and sculpt the sound of single instruments, big ensembles as well as whole orchestras. Different halls ("Venues") have different colors, not just different reverb lengths. Especially the "Studios and Soundstages"-RoomPack might be what you're looking for.
In addition, we have built-in lots of "wisdom" about Vienna Instruments into MIR, like the individual, hand-made "Character Presets" for almost each and every instrument we ever released. I have chosen descriptive names for them, so "Lushness" or "Warmth" is actually one of the MIR-instrument-presets for many of our string sections.
.. the easiest way for you to know wether MIR is what you're after (or not) would be to download the demo version of Vienna MIR right now. MIR Pro will just add to its underlying concept, not take away from it. 😉
Kind regards,
