If will smith was Mace,He'd be trying to eliminate all the droids in the Galaxy cus he thinks they are taking over and the Galaxy, and the Jedi aren't really needed anymore. "Anakin, their ain't no way in hell your gonna be a Master", I mean it's not like I dislike the guy but he can't be very serious, sure star wars has some comedic stuff in it, but Mace shouldn't be the one saying or doing any of it, Now Sam can be a serious character, unlike Will who has to crack a joke no matter what movie it is.
wasn't the part written in deliberately for sammy jackson?...i remember when he was on TFI friday on channel 4 years ago and he said that he would love a part in the new starwars films even if it meant he was just some dodgy stall keeper on tatooine...the next day he got a call from george lucas saying that they would get a part for him...
