Chrises Evans and Hemsworth cheer on a young Cap to mark World Down Syndrome Day

It’s not every youngster who can claim shoutouts from not one but two Avengers on the same day.

But one young man got just that this week after his dad, Adam Morris, posted a picture of his son on Twitter reenacting an iconic scene from 2019’s “Avengers: Endgame.” That’s the one in which Captain America — played by Sudbury native Chris Evans — lifted Mjolnir, the hammer usually wielded by Chris Hemsworth’s Thor in the Marvel movies.

Avengers fans know that “Whosoever holds this hammer, if he be worthy, shall possess the power of Thor.” And this young man was declared “definitely worthy” by Hemsworth himself in a tweet on Tuesday.

That prompted a response from Evans, who declared that the young Cap was “making it look easy!”

The two tweets together had amassed more than 10 million views as of Wednesday morning, bringing a slew of accolades for the cute cosplay, and drawing some belated attention to World Down Syndrome Day, which took place March 21 and which Morris, a student pastor in Georgia, tagged in his initial post.

World Down Syndrome Day has been observed by the United Nations since 2012, according to the program’s website, which also notes that “the date for WDSD being the 21st day of the 3rd month, was selected to signify the uniqueness of the triplication (trisomy) of the 21st chromosome which causes Down syndrome.”

Evans is of course no stranger to supporting children, even outside the movies: His Boston-based charity Christopher’s Haven provides temporary apartments and a recreation area for families of children being treated for cancer in the city.
