Encouraging you to find it. I can't live knowing I've missed a behind the scenes detail? Especially if it's concerning Aragorn and Arwen.
Hell I bought that damn lego set
Plot twist: It's because Jonah Hill wasn't willing to kiss Lauren London. >

Many movies have done this. >

Many? I’ve never heard of one before, which ones has it happened on? >

It goes way back. CGI is new, but in the past they used props. See: LOTR (i forget which one) scene where Aragorn kisses Arwen >

It has been done many times before, but not in LOTR.
The set drama surrounding the kiss was that they finished shooting with Viggo Mortensen, and wanted Liv Tyler to kiss a double for the end of Return of the King. She refused and they brought him back in. Despite her saying she hated kissing him because his beard lol. >

They put a clear plastic thing between their lips. I remember seeing it in the extra stuff >

I'm sorry I just don't remember that, and I've seen those behind the scenes clips a great deal. Maybe a different movie? >

No, it was that movie series. It would be an odd detail to make up lol
