Oscar Angulo, the siblings’ father, was strict. For years, he didn’t let them leave their apartment on their own. On the rare occasion when they went out as a family, the kids were told not to speak to anyone. The internet was also off limits. But Oscar loved movies, so he recorded a massive library on VHS and DVD – about 5,000 films in total. The siblings would watch the same films over and over and, after fiercely debating their collective Top 40, they decided to start recreating some of them.

“We always say lines from our favorite films and we thought, why don’t we do those films, be the characters,” Mukunda says. Without a computer or even a typewriter, he had to handwrite all of the individual scripts. “It took me a week to write Goodfellas, a week to write The Dark Knight, about five to write The Dark Knight Rises, two to write Batman Begins. Writing that and hurting your hand, it’s torture, but seeing the result is everything.”

The siblings now star in their very own film – albeit a documentary.  The Wolfpack, directed by Crystal Moselle, won the Grand Jury Prize at this year’s Sundance Film Festival. Moselle first encountered the kids on one of their very first unsupervised forays out of their apartment. She took them to an internet café where Mukunda used the internet for the first time. “I just googled The Dark Knight and found out stuff I had no idea existed,” he says. “That’s the first thing I googled. I’ll never forget it.”
