WATCH: Arthur Darvill sings Doctor Who-themed version of 'Let It Go' from 'Frozen' [VIDEO]

"Let It Go" is clearly one of the biggest songs of the year with plenty on Internet parodies popping up every week or so, but Doctor Who fans will most likely enjoy this new cover most of all. Arthur Darvill, the actor that portrayed companion Rory Williams on the BBC series, debuted his own rendition of the Frozen song entitled "The Ballad of Arthur Darvill."

While appearing on BBC Radio 1, the actor who is currently taking the stage by storm in Once performed his own parody of the biggest song of the year. Whovians know that Arthur has quite the sense of humor, so you can imagine how this song turned out.

The song isn't exactly about the hit time-travelling series, though - it's more about Darvill dealing with the fact that he used to be on the show and how people only talk to him about this one role. We're used to hearing about actors and actresses acting this way after a big role takes over their life, but at least Darvill has a great sense of humor about it!

Soon, this ballad turns into a promotion for his stage work. We're not too mad about this since he's on the radio and it's a great time to plug a show, but we want more Doctor Who references!

It's still great to hear Arthur singing about his time as Rory Williams. We all still miss the character, but we should really let it go...
