Characters
LEGO Star Wars on the Wii has countless characters that span the whole of the Star Wars universe.

Several vehicles can be unlocked for certain stages. Like the characters, you can unlock these vehicles (for free) by entering the following codes while inside the Cantina:
Imperial Shuttle - HUT845
TIE Fighter - DBH897
TIE Interceptor - INT729
Tri-Fighter - AAB123

Unlocking Indiana Jones
While not part of the Star Wars Universe, Indiana Jones is another beloved character from the mind of George Lucas. You can unlock him for play in LEGO Star Wars by first going into the Cantina's "Bonus Room," where you will have the option of watching the trailer for the "upcoming" (it has since been released) LEGO Indiana Jones game. Upon completion of this trailer, the character of Indiana Jones will become available for purchase in the game's store for 50,000 studs.
