The Nintendo Short Cuts contest actually has a few pretty decent entries, and here's one of 'em. Punch-Out!! done up as a movie trailer, and in live action. 80's rock-lite sounding music plus Von Kaiser's over-the-top acting skills equals a contender that refuses to go down.
At four and a half minutes it clocks in longer than your average trailer, and lacks a bit of what you can find in this other live-action version ... but you gotta give them some credit for originality in the script. Who knows, with Hollywood remaking nearly everything they can, a Punch-Out!! movie might actually happen.
