Warner Bros. paid the then-unknown director in weekly installments for 1971's "THX 1138."

George Lucas' path to movie billions began rather humbly and can be seen in the hidden vaults of Warner Bros. Corporate Archive, a facility kept away from most prying eyes deep in the Valley.

Lucas first joined Warners' payroll when Francis Ford Coppola brought his friend on board as an assistant on 1968's Finian's Rainbow. Studio payroll memos highlight how Lucas was getting paid $110 a week and was even bumped up to $125 per week.

Warners' internal memos between executives highlight the young Lucas' interest in sci-fi. A year later, Warners came aboard to distribute Lucas' THX 1138, paying him $2,500 in installments.

The financial memo was among the movie treasures The Hollywood Reporter saw as it was allowed an extremely rare peek into the workings of the little-known but hugely important division, whose facility houses decades' worth of costumes, props, scripts, correspondence, memos and animation art -- almost anything to do with a Warners movie and, more recently, a Warners-made television show -- is saved and stored.

Among the other treasures: a slew of batmobiles, replicas of agent Smith from The Matrix, puppets from Gremlins and Tim Burton's Corpse Bride, and George Clooney's batsuit from Batman & Robin (seriously!)
