Underexposed footage cannot be corrected in post anymore than overexposed footage.
The Panavision camera has a much higher dynamic range than your average consumer cam, so it's bad advice to try and match the "tone" by underexposing. By the time you get to that point you'll have lost a great deal of image information in the midtones and the shadow that cannot be recovered.
The best advice is like Timur already stated: expose properly. Try your best so that the image is not blown out, but you'll usually have to compromise or bring in additional lights or bounce.
