Although many fans assume the image was from the first movie, Mark said it may have never happened in the film itself.
He shared the image – and an explanation – on Twitter.
“This makes me cringe every time I see it,” he wrote.
“I don’t remember doing this in the movie. I think it’s just an on-set production still, otherwise Obi-Wan wouldn’t look so remarkably unconcerned.”
Except that wasn’t quite the end.
Mark also surprised fans with an unforgettable de-aged appearance in last year’s season two finale of The Mandalorian.
