If you know your Marvel stuff you'll probably be aware that John Krasinski was for a time in the running to play Captain America.
The role would eventually go, of course, to Chris Evans. Though John Krasinski isn't doing bad for himself, mind you, now headlining 'Tom Clancy's Jack Ryan' on Amazon.
He's directing too, with 'A Quiet Place Part II' hitting cinemas next April after being postponed.
Now a new deepfake imagines what 'The Office' star would have looked like as The First Avenger.
The edit is super effective as the actor blends seamlessly among co-stars Robert Downy Jr., Mark Ruffalo, Sebastian Stan etc.
The video was posted on YouTube by Shamook (which previously put Harrison Ford into 'Solo: A Star Wars Story' via deepfake) and is nearing 450k views after 5 days.
It uses footage from 'Captain America: The First Avenger', 'The Avengers' and 'Captain America: Civil War'.
