The following is an excerpt from Chris Pratt Visits Children's Hospital Los Angeles in Costume as Star-Lord From Guardians of the Galaxy
Chris Pratt doesn't just play a hero—he is one!
The actor worked with Marvel and Children's Miracle Network Hospital to arrange a special screening of Guardians of the Galaxy for patients, families and staff at Children's Hospital Los Angeles Wednesday.
While the movie played, Pratt snuck out and dressed up as his character, Star-Lord.
The 35-year-old actor spent more than three hours in full costume and handed out movie-themed toys. Pratt also visited patients in the Bone Marrow Transplant Unit, the Children's Center for Cancer and Blood Diseases and the Pediatric ICU, as they were too sick to join the movie screening that afternoon.

The best part about this charming act of charity is that Pratt did it true to Star-Lord's M.O., mixing something good with something bad. "A bit of both," if you will. See, the reason Pratt was able to swagger into the Children's Hospital in full Star-Lord regalia was pretty outlaw. He stole it.
