Robert Downey Jr delights brave boys at Captain America: Civil War premiere
Robert Downey Jr greeted two pint-sized super heroes at the Captain America: Civil War premiere after they won his heart with their stories of battling life-threatening illness.
Seven-year-olds Daniel Keyte and Ethan Miller were invited to join the Iron Man actor at the red carpet alongside a host of Hollywood stars in London on Tuesday.
Downey Jr first met fan Ethan, who suffers from the rare blood disease ITP as well as type 1 diabetes, during a visit to Great Ormond Street Hospital.
After posing for pictures dressed in an Iron Man costume his father, Lee, said the youngster was "over the moon" to meet his idol.
Daniel was invited to the star-studded event after his mother, Vicky, messaged Downey Jr to say her son was feeling unwell and unhappy.
In response, the actor dressed as children's character Tigger and posed for a photo.
He wrote on Instagram: "When I'm in the dumps, I've found this little getup to be helpful. P.S. Would you like to come to the LA premiere of Captain America: Civil War as my guest? If so, have your people call my people. All the best."
Instead, it was at the European premiere in London on Tuesday night that Daniel got the chance to meet Iron Man, aka Tony Stark.
Alongside a picture of her son and the megastar posing together on the red carpet, Vicky posted on Instagram: "It's happened!!!"
Earlier in the day, she shared an image of the car sent to collect her son, writing: "And so it begins! Daniels big day is finally here and so is surprise number one, Daniels own personal driver in a beautiful car."
Ethan was among several children to meet Downey Jr on the GOSH cancer ward on Monday.
It is one of the world's leading children's units, treating young patients with rare, complex and life-threatening conditions.
The visit was organised by Disney officials, who have worked with the hospital's charity since 2008, raising more than £10 million for the unit's redevelopment.
After the hospital visit, Ethan's father Lee said: "Ethan has been in and out of hospital a lot in the past three years. He watches the films all the time and virtually lives in his Iron Man costume.
"Ethan was over the moon to meet his hero and it has really helped to lift his spirits."
