Daniel Radcliffe orders Jimmy Fallon to do the Gangnam Style dance and the famous host did.

Harry Potter guests on The Tonight Show with Jimmy Fallon to promote for his upcoming film 'Victor Frankenstein' which will be available in theaters this coming November 25. The 26-year-old actor helped the audience of the show convince the late night talk show host to do the dance which became viral in 2012.

The audience started convincing Jimmy Fallon after opening up the topic about 'Gangnam Style' dance. The host started the show by talking about the dance craze which gained national recognition in Korea.

"South Korea is building a giant monument to the song 'Gangnam Style,' which will feature two overlapping wrists, a signature move of the 'Gangnam Style' dance," Fallon stated.

After hearing him out, one of the audience stood up and asked the talk show host to give a sample of the dance craze. The 41-year-old host refused to do the 'Gangnam Style' dance. Another audience stood up to help convince Fallon but again, the host refused.

"Sorry to burst your bubble here, but I was just going to tell a joke about that story," Fallon reasoned out. He even pointed out that they can't command him to do anything.

Then, Daniel Radcliffe's voice appeared surprising everyone. Like a military commander, the 'Kill Your Darlings' star commanded Jimmy Fallon to do the 'Gangly Style.'

"Now, listen to me, James Fallon: I didn't swim here all the way from England not watch you not do the 'Gangly Style' dance, OK? Hit the music," explained the actor. Fallon had no choice so complied with the order.

After seeing the host dance, Daniel Radcliffe expressed his satisfaction for Fallon's performance.

The Harry Potter movie series actor and Jimmy Fallon then played the 'Water War' in which whoever gets the smallest card gets a glass of water thrown at his face.
