If you thought you'd seen the best of the 'Let It Go' mashup viral videos, you haven't. A new epic 'Lord of the Rings' treatment is the one video to Rule Them All!

Missed the 'Game of Thrones,' 'High School Musical' and 'Fifty Shades of Grey' versions? They're terrific, and you should watch them. We'll wai ...

But those videos used existing footage to illustrate their parodies of the 'Frozen' hit. The 'Lord Of The Rings: Let it Go Parody' by the Hillywood Show on YouTube takes things one step further, filming new scenes in an impressive re-creation of Middle Earth. Its high-end production value pretty much perfectly captures the look of Peter Jackson's 'Lord of the Rings' trilogy.

Creators Hilly Hindi and Hannah Hindi star as Hobbits Frodo and Sam, as Sam implores his friend to let the One Ring fall into the fires of Mount Doom. Sample lyric: "Let it go, let it go, can't carry it any more / Let it go, let it go, turn away and leave Mordor."

It's spot-on for 'LOTR' fans, even if it's clear that the Hillywood Show's budget was stretched with the casting of its Gollum. (But he's preciousss.) Watch the clip above!
