No Body Prod film ever had a Hervé Handsome credit, it was always Hervé Bodilis, since he IS in fact Body Prod. That "Handsome" name was from the beginning a High Octane creation, for the North American market, to ensure the US distributor which had acquired the North American rights to the films also owned the director's name so that in case their agreement was dissolved, Bodilis couldn't hope to build on the reputation accrued to him in the US from those films.
High Octane just followed the template already introduced by the Falcon International Collection, at the beginning of the 90s: sustain for as long as possible the fiction of a Californian "studio" actually making films in Europe (as opposed to just buying and importing products). The people at Pacific Creek pulled the same stunt on Robert Boggs with their Alain Eclair charade in 2003.
