This was what made the scenes seem authentic even if they were entirely fictional. Moreover, Jesse disobeying an order to complete a mission, and Tom filing an accurate report even if it got Jesse in trouble, are both consistent with their respective characters. Though they're factually false, they shine a brighter light on the racism Jesse faced, and how he dealt with it through sheer heroism and tenacity.
He managed the Fremont, Stardust and Hacienda casinos in Vegas. The plot was actually inspired by a real-life person, known as Frank Rosenthal. It was directed by the prestigious Martin Scorsese and it starred Joe Pesci, Robert De Niro and Sharon Stone. While these scenes are not 100% authentic to Devotion's true story inspiration, they do help in establishing the most crucial aspects of why the real Jesse Brown is important to Navy history. The famous hit movie Casino was released in the year 1995. Both of these moments are fictional, as there's no record mentioning that Jesse Brown blew up a bridge and disobeyed a direct order, or that Tom Hudner filed a report about it. After the mission ended and both men are safely on land, Tom praises Jesse in the report, but Jesse tells him that it will likely just be used by their racist superiors to deny him promotions in the Navy.
During one of the flying missions in Devotion, Jesse disobeys Tom's orders to retreat and then blows up a bridge by himself.
