His "unmistakable charisma and talent" led to him being "asked to do a trilogy of short films playing a character that was written specifically for him," which landed him more roles later, his bio added.
While promoting CSI: Miami back in 2009, Ellingson told The Philippine Star, "I never had the same [childhood] experience with my friends. I never had more time with them. However, my childhood was a cool one. I was busy doing the things I love."
He added, "I had no regrets because I found my passion for acting early on."
