Colin Farrell's son James stars in new HBO doc

The trailer for HBO's upcoming documentary, 'The Slightest Touch,' offers a rare look at Colin Farrell with his eldest son, James, 23. James, who has Angelman syndrome, shares a tender moment with his father in the preview. The documentary primarily focuses on Farrell's friendship with Emma Fogarty, who has lived with epidermolysis bullosa since childhood.

Farrell and Fogarty embarked on a challenge to complete the Dublin Marathon together, an event depicted in the trailer. Farrell notably assisted Fogarty during the race's final kilometers. The actor, also father to 17-year-old Henry, has previously championed support for adults with intellectual disabilities through the Colin Farrell Foundation.

He has emphasized the need for kindness and respect for individuals like his son, James. Farrell has also spoken about the significant challenges families face when young adults with intellectual disabilities transition into adulthood without adequate support systems. He expressed pride in James's personal achievements, such as learning to feed himself, viewing his son as "magic."
