Ryan Reynolds Writes Touching Letter In Remembrance Of 13-Year-Old 'Deadpool' Fan Who Died Of Cancer

"I wish he could've stuck around a lot longer."

Ryan Reynolds made headlines last week for his humorous dad tweets, but this week, he's making them again for another, even more heartwarming reason.

Reynolds penned a bittersweet tribute letter about his friend Connor McGrath, a 13-year-old "Deadpool" fan, who lost his three-year battle with leukemia this week.

Through the Make-A-Wish Foundation, McGrath saw Deadpool before anyone else. Reynolds, who played the title character, surprised him in Edmonton, Alberta, with a rough cut of the film. 

"There were still huge sections with wires we hadn't yet painted out, jokes which weren't working (and still aren't) and green screens," Reynolds wrote in his note. "Connor didn't seem to mind. And I'd never felt luckier to get to be Wade Wilson." 

Reynolds admired his young friend's strength, but mostly his sense of humor. The pair even called each other by the nicknames of Bubba (McGrath) and Bubba2 (Reynolds). 

"In a certain sense he WAS Deadpool," Reynolds continued. "Or, at least everything Deadpool aspires to be; balancing pain, fearlessness, love and a filthy (filthy!) sense of humor in one body." 

"I wish he could've stuck around a lot longer."

Their unique friendship extended beyond that initial visit and viewing. Reynolds returned six weeks later, but, unfortunately, McGrath's cancer had intensified. 

"After my visit, I didn't know if I was saying goodbye or see ya later. Sitting here now, I realize it was both."

McGrath passed away on April 26. Though lost, he would not be forgotten. Reynolds made darn sure of that.
