Nick Jonas Teams Up With Jack Black for Horrible '80s-Style 'Jumanji' Theme Song
Sony Pictures
'Jumanji: Welcome To The Jungle' Premiere

Dwayne "The Rock" Johnson, Karen Gillan, and Kevin Hart are not impressed.

Forget the trailers, the press junkets, the interviews and anything else you know about "Jumanji: Welcome to the Jungle." Nick Jonas and Jack Black have everything you need in the music video for "Jumanji Jumanji."

If the pair have their way, it may not even be subtitled "Welcome to the Jungle" anymore. The Guns N' Roses theme song is nice and all, but Black channeled every bit of his Tenacious D past in crafting the perfect send-up to 1980s glam-rock overload both in the song and its accompanying music video.

Think "The Final Countdown," but even worse.

In the new music video posted on Jonas' YouTube channel, the pair are very excited to share the final product with castmates Dwayne "The Rock" Johnson, Karen Gillan, and Kevin Hart.

"I think we finally cracked the code on the theme song for the movie, and we got this music video that we put all of our creativity into," Black tells his co-stars in the sketch. "I think you'll agree that we did it."

Perhaps in a nod to the original 1995 film, but more likely to truly capture the kitschy awesomeness of their magnum opus, the special effects for the "Jumanji Jumanji" music video are absolutely awful. Luckily, there are plenty of power chords and wind machines to distract you from it.

There's Black literally rocketing into space, here he is rocking out with Jonas on digital neon guitars, and look at all the cool jungle critters they're totally interacting with! But it was't just a visual tour de force; like any good theme song, "Jumanji Jumanji" told us who the characters were and what they were about.

Johnson and Gillan try to compliment their co-star's creativity and fine use of wind machines, but Hart just tells it like it is: "I guess I'll address the elephant in the room -- that was shit."

See if this song makes it into the final cut somehow when "Jumanji: Welcome to the Jungle" hits theaters on Friday.
