Ryan Reynolds posted on Instagram photos of himself spending time with children from the Make-A-Wish Foundation and Children's Wish Foundation on the set of "Deadpool 2."

"One of the best parts of playing the Big Red Jackass is welcoming @makeawishamerica and @childrenswishfoundation onto set," the actor said alongside the photo set which features Reynolds posing with families, talking with the kids and sharing autographed toy swords.

"Deadpool kicked Cancer in the taint, but these kids do it for real every day. These foundations make dreams come true for a lot of of super-brave kids. They also make dreams come true for parents, who just wanna see their kid smile," he continued.

"HUGE thanks to our Prop Master, Dan Sissons, for making sure every kid left with his/her own sword. (Bamboo versions. Not stabby-stabby versions.)"

Reynolds' character in the Deadpool, Wade Wilson, is diagnosed with terminal cancer in the film before he undergoes an experimental mutation that leads to him becoming the mutant mercenary.

Reynolds previously paid tribute to Deadpool fan Connor McGrath who he met while the 13-year-old battled cancer.

"Deadpool 2" is set to arrive in theaters on May 18.
