FAST Dice Trivia Game

I'm curious to know the community's impressions of a simple dice game I'm currently shopping around...the goal was to design an all-dice trivia game, where it's not just about WHAT you know, but how FAST you know it!

The game is for 2-8 players and scaled very nicely given its "party" kind of gameplay.

The game is super simple...roll the d12 Category Die, followed by the 6 d6 Letter Dice.

Players race to name something befitting the category, for instance Film could be a movie title, an actor or a film character. Grab the dice as you name them, until all dice have been grabbed. If a player disagrees with an answer, they ca shout "REROLL" and point to the offending player, who then re-rolls the dice they incorrectly grabbed back into play. This may be made easier by the presence of a judge player, who oversees the round, leaving players to focus on the game. Highest scorer plays the judge on the next round...

Score 1 point for every dice you grabbed, then return all dice and start over again. Play to a total of 10 points, with roll-offs between tied players.

The 12 categories are:
Film, TV, Music, Video Games, Literature, Science, Geography, Sports, Animals, Food, History and Tech.

The Letter Dice have been optimized to feature the more common letters, no Q,X,Z or other tougher letters.

I'd really appreciate any thoughts you might have...I wanted to design a fast, fun and simple "pocket" dice game with a unique twist, that puts player's brains to the test, and can be busted out anywhere for some quick fun.

Also...what would you name such a game?? All I have so far is "Rollcabulary" and it just doesn't feel right. "Speed Roll Trivia?" "Trivia Roll?"

Thanks all!!!
