He previously said that making Deadpool was an '11-years-of-a-dream come true'، daily mail reported.
And Ryan Reynolds، 40، has now made one young fan Daniel Downing's dreams come true after he video called the five-year-old، who has months to live.
After hearing about the youngster's terminal illness، the Hollywood actor - who he calls his hero - organised a phone call in between filming Deadpool 2 to the Plymouth native.
The Marvel fan was sadly diagnosed very aggressive cancer called Pontine Glioma and at the start of the month it was confirmed that he had an inoperable brain tumour.
And following the devastating diagnosis، his dedicated family and friends are determined to make his final months as memorable as possible، with a phone call from father-of-two Ryan being one of them.
In the emotional video، the Canadian actor - who is married to Blake Lively - can be seen speaking the adorable boy، who tells him about how 'poorly' he has been while surrounded by his mum، step-dad Ady، older brother Jack، and two of the family's baby sitters.
Suddenly being able to chat to his idol، the sweet boy cheekily asked if he could FaceTime him to show off his Deadpool T-shirt.
Seeing his fan face-to-face، Ryan enthusiastically shared: 'Ah that's awesome، what an awesome T-shirt! You know I'm the only guy who doesn't have one of those T-shirts، I need to get one of those.'
After talking about his love for the comic-book adaptation، Ryan asked Daniel if he wanted to see a sneak peek at the set of the upcoming second installment of the film franchise، which is set to be released in 2018.
Ryan began: 'Yeah I am outside، you know what I doing right now? I'm filming Deadpool 2. I'm about to walk into the set and shoot Deadpool 2.
'Do you want to walk me? I'll take you onto the set for a second. It's going to be good، it's going to be a little dark in here، OK?'
Following the excitement، Daniel's mother Stephanie spoke to the Plymouth Herald about the heart-warming conversation which lasted for 15 minutes.
'Daniel picked up the phone and Ryan asked if he knew who he was،' she said. 'As soon as Daniel realised، he asked if he could FaceTime him and then he was very، very hyper.
'All the camera crew waved hello and Daniel had his Mr Pool t-shirt on (like the Mr Men but for Deadpool). Daniel was telling Ryan how poorly he'd been and how his friends had helped him feel better.
Adding: 'He had to dash off to film، but that was good really - Daniel gets tired very quickly.'
Friends of the family are currently raising money through a JustGiving page to help with his palliative care at Bristol Royal Hospital for Children، 200 miles from his family home.
