Vega Brothers VS Gecko Brothers

Hmmm, has anyone considered the FACT that QT wanted Madsen to play Vincent Vega, and unless vincent and vic are identical twins thats pretty hard to imagine them as brothers (madsen was filming the self confessed worst role of his life).

Can i just say then that originally they were not meant to be brothers, were they meant to be the same guy, i think not because of the massive death scenes in both films, QT, sort your ideas out man, if something goes wrong dont go half assed
