These often find their way into the public domain as pirate copies and are sold at profit. That is certainly a criminal case of copyright infringement.
Yes. My involvement with the Utah Film Society and the Sundance Film Festival grants me early-screening privileges for most feature films. For example, last week I was invited to a private screening of Kevin Costner's new film
Draft Day (surprisingly watchable for someone who doesn't like either sports movies or Costner). Cell phones and any cameras are collected at the door, and there is a sheriff's deputy present.
Technically, merely recording the screening is not criminal in the U.S. since the "commercial gain" element of the crime is unsatisfied. But the way the cases work out, recording a screening of an unreleased film is
prima facie evidence of intent to gainfully distribute, which puts you on the hook for "attempt to..." offenses. In most U.S. states, for any criminal offense X, you can be charged with "attempt to commit X," which is one degree lesser an offense than the original. So the technicality rarely holds, and legislatures and courts in the U.S. come down particularly hard on copyright violation.
