It feels like the scene is pasted in as an afterthought, perhaps to give Jesse Owens a bit more significance?
He symbolized everything the Nazis were against.
From Wikipedia:
"He achieved international fame at the 1936 Summer Olympics in Berlin, Germany, by winning four gold medals: 100 meters, long jump, 200 meters, and 4 × 100-meter relay. He was the most successful athlete at the Games and, as a black American man, was credited with "single-handedly crushing Hitler's myth of Aryan supremacy".
This is what I'll say, if people in the U.S. don't know who Jesse Owens is, then they don't know much of anything...or worse, don't care to. His name is always coming up here and there nearly as much as Jackie Robinson's. There's been documentaries about him, TV movies about him, he's always portrayed in Olympics documentaries and there was a 2016 film, titled Race, about him which also starred Jason Sudekis of Ted Lasso.
Like I said in a previous post, I don't know if these rowers actually did know who Jesse Owens was, and if they did, this portrayal actually occurred. If the scene in the movie as portrayed actually happened, I say it was really awkwardly done. It would have played better if they showed a couple of the rowers pointing Jesse Owens out and said to one another, "Look, there's Jesse Owens, the track star." But it played more like the filmmakers wanted the audience to know and that felt insulting in some way.
I just looked up to see if I could find out and I saw an article that had interviewed the screenwriter, Mark L. Smith. He was asked if the Jesse Owens stuff was in the book and he said,
"No we added the stuff with Jesse Owens and I added a little bit more interaction with him on the ship over, on the ride over, but we just didn't have time for it in the movie to keep it in."It still doesn't really answer my question of whether or not the rowers actually had any interaction with him, on the boat or at the games, but if it isn't the book, which you'd think a reference of that would be mentioned, then I'm guessing it didn't happen.
By the way, I mentioned somewhere that this movie took a long time to get made and went through several hands and one of those was that the movie was originally going to be directed by Kenneth Branagh. In this case, I'm glad George did it.
