weird movie coincidence

[Voltron87]

I went to see two for the money today, and it sucked bad. real real bad, don't see it. But during the previews there were two that stuck out. the first is for "Annapolis". Its about a kid at the naval academy. The preview is a lot of loud music, pushups in the rain, running, sargents yelling the typical macho stuff about duty and honor and serving your country. The kid is some 20 year old white kid played by some guy who has been in a bunch of movies but I don't know his name. Now, theres this sargent/teacher there who puses the kid real hard and the movie is about the sargent being rough on him "because i see myself in him". He's played by Tyrese Gibson (is that his last name? I know the first is tyrese), very black.

Second movie: Jarhead. This time Jake Gyllenhal is the white kid recruit, in the marines this time. Preview opens: loud music, pushups in the rain, running, sargents yelling the typical macho stuff about duty and honor and serving your country. running over obstacle courses and getting dirty. Eventually the movie takes place in iraq during desert shield. This time: black superior is Jamie Foxx (black). Exact same relationship.

I just thought this was really weird, there are two movies coming out in the same month with extremely similar settings (boot camp) and extremely similar actors, one white recruit and a black superior who seem fairly identical. They both opened exactly the same way and had the exact same feel, voice overs about being picked to be badass and everything.
