Haven't seen that movie about young Indy and Dr. Quatermain, but for the record, I don't really much like the "childish" brand of cheese and silly, and the kidactors (save for Malfoy) kinda sucked in that movie, but I thought Ian Hart (the guy in the purple turban) was pretty fucking awesome.
So's almost any of the adult actors in this series, for that matter :D
As for Qui-Gon's ghost, I don't watch CW but, for some reason, I can't get this one image of Jinn's Shadow wandering around the dreary widths of Ralph's Hammes out of my head right now :D
