It bears a striking resemblance to a half-decent Canadian film called “The Last Casino”. Here’s the plot summary from IMDB:
One deadbeat teacher discovers that three of his students are great math wizzes and decides to teach them how to count cards and make lots of money. As they learn how to play the casinos, things get tricky when the debt owing teacher informs them that their front man wants restitution for loses (of supposed $500,000 Canadian) in about a weeks time. The three students decide to hit all the major casinos in Ontario and Quebec until discovered.
Sound familiar? I couldn’t find a trailer online, but here’s a clip from early in the film:
Much like “Munich” and “Sword of Gideon”, it always bums me out a little when big budget movies replicate the stories of smaller and independent films. Most viewers never know that the apparent original work they’re watching is, in fact, highly derivative. And it’s a safer bet for the artists involved in the remake, because the creators of the original made many of their mistakes for them.
