As the highest-grossing animated feature of all time, just about everyone has seen Disney's film Frozen, as well as every Youtube cover of the film's popular songs.
One family in Utah, United States has cashed in on the film's success making up to $10,000 a month from their covers of Frozen songs.
It all started when 22-year-old Robbie Bagley was watching Frozen and realised that his little sister Mia Bagley, 9, closely resembled Princess Anna from the film.
Casting Mia as a young Anna and sister Ari Bagley, 14, as an older Anna, he began planning a cover video of Do You Want To Build A Snowman?.
"My little sister looks exactly like her [Anna]. Our whole family acts and sings so I knew she could do it. I got a group of friends together, we decided to film it and it went big," says Bagley.
While Bagley has always enjoyed filming, he had limited resources when he first started creating the videos.
"I did most of my recording with a Garage Band mic and a pop filter made out of a hanger and nylon tights, which is cheap but it works and that's kind of how it started," says Bagley.
"I'm mainly an editor and a director, but when we first shot Do You Want To Build A Snowman?, I didn't have a nice HD camera so I called up my friend. He had a friend who had a $400 camera and we used that for a lot of our beginning videos," he continues.
Bagley uploaded their first cover video in March this year to his Youtube channel Working with Lemons. Since then, the video has had over 90 million views worldwide.
The creative process behind the videos is very much a family affair. Bagley works with his family and a few close friends to produce, direct and edit the videos. His mother also sews the costumes.
"Working with my family has probably been the best part of it," says Bagley. "And it's wonderful because we've been able to also make some money doing this which allows us to make more videos and it's been able to help my family get to LA, get signed with some agencies and do some auditions."
In the process, the success of their covers helped secure younger brother Anson Bagley, 11, a small part in Criminal Minds' Halloween episode.
It has been a big year for the Bagley family, but they show no signs of slowing down. Bagley says they are currently working on a cover of Frozen's hit song Let It Go to be completed by the end of December. The family also plans to cover songs from Tangled and other Disney films.
