Academy Award Trophy
Rise from the last spot 5 seconds before the finish.
You will get this trophy (and again, the associated in-game medal of the same name) by going from last to first at the very end of the race. It is fairly likely you'll get this naturally if you're in last, because the game gives some nice boosts and weapons to help you catch up. However if you've not accidentally got it, simply replay an earlier career race and save a good boost until right at the end. The mission "Jungle" works well for this, simply stay in last place until just before the final bend and boost all the way around the bend and over the finish line. I was unable to unlock this during party mode with 2 controllers.
