Collin Farrell has offered a rare glimpse into his life looking after his son James, 20, who has special needs due to Angelman syndrome.

James was born with the neurogenetic disorder, which causes developmental delays, impaired balance and other issues.

His own case is severe enough that he is nonverbal and requires the help of a live-in caregiver to accomplish his day-to-day tasks.

Now, as Colin launches a foundation for other adults with intellectual disabilities, he has spoken touchingly about his love for his son.

‘I want the world to be kind to James. I want the world to treat him with kindness and respect,’ the 48-year-old actor told People.
