Crowd chant: "Two Jedi enter! No Jedi leaves!"

I love this! Though I think I may have Poggle say it.

The arena monsters could be redubbed for comedic effect. Godzilla sound FX perhaps? The cat like creature could sound like a housecat...

Ripplin suggest the cat thing (and Godzilla) as well. I'd like to do a different non-threatening sound for each of the monsters, but I'll have to see how easy it is to remove the original sounds.

If you want to speed things along, using the previously mentioned Nute Gunray "Get on with it!" line from the deleted scene could work here.

I like it!

And don't forget the Shaft theme song for when Mace makes his entrance. ;)

Perfect :-)
