Continuity mistake: When Snake takes his full-court shot, you see the clock is already at ten points, as he should only have eight points. Basically, they already knew he was going to hit the shot.
Continuity mistake: Snake jumps off the surf and into the car with Eddie. They fight as the car drives down an alley. There is an old man in front of them at one point, who steps out of the way of the car. They continue driving perhaps a block and stop. They speak for a moment, then Snake continues driving, past the same old man, and past some of the same parts of the alley they just passed. (01:09:00 - 01:09:35)
Other mistake: When Snake starts up the sub, the turbine is referred to as being at 75% power. The display shows "0.75" which is 75%, but there is also a "%" symbol above the numbers. Either the display is bizarrely constructed or the power output is stated incorrectly. (00:21:20)
