A Colorado boy has paid tribute to his favorite movie with a photoshoot.

Elijah Perman, 5, is a huge fan of the 2009 Pixar classic “Up." His mother, part-time photographer Rachel Perman, says her son is "obsessed" with the movie.

When Elijah and his twin sister Emilee turned 5 recently, Rachel decided to do what she called "magical shoots" for their birthday.

"I was diagnosed with cancer right after my twins were born and had fears if I would even get to see their 5th birthday," she told Fox News in an email. "... SO for their 5th birthday I wanted to celebrate the things they love with photos! It's a celebration for me and them!"
