<human>: This is a xpost from the UK thread, but I guess it doesn't hurt to ask here since this might be something that applies to the US since the movie is from Hollywood? I am not sure...

Copy and paste from the other thread:
I'm a  student from around Slough and want to get into my dad's line of work, which is editing. He sometimes gets to work on bigger stuff and gets invited to see trailers or rough cuts of films that are shot around here.

I'm a big Star Wars fan, and my dad knows that, so he took me and a friend (we'll name him Tom) to Pinewood today. I got to see the new Rogue One Trailer that is coming out with a certain movie with a bat next month and it was AWESOME.

My dad told us not to take any pictures or videos once we got on the lot, but Tom just sent me a snapchat of some video he shot when we looked at the trailer, and he said he's going to upload it tomorrow. I don't know what to do. I told him he can't do that and he'll get my dad in trouble.

I just turned 18, so I'm kind of freaking out. Will I get in trouble? Will my dad? Is it illegal to leak a trailer?

Give me the gist of the text in a nutshell
<bot>: saw awesome trailer before it's released w/ a friend and he recorded it and now wants to put it on YouTube. Who gets in trouble?
