|Addendum to Derek's post: it is most definitely a fake movie download. Do not waste any more of your time. There is no such player that will allow you to watch the download. You have been had/tricked/punked/scammed.|
Delete that download as it is useless (at best) and is taking up as much drive space as a genuine, watchable movie would. Size does not matter (in this case).
This "prank' has been going on for several years.
