thanks Barbel, that's extremely obscure casting details, you must have this movie memorised well!
I'm now thinking, why wouldn't Drax invite Goodhead herself? she's physically very fit (we see her punching out minions), she's got Lauren Bacall style classic beauty, and she's hella-smart ... wouldn't she qualify as perfect specimen for his breeding scheme?
but no, he prefers Titled aristocrat chicks, the type Bertie Wooster is always trying to get out of marrying ... probably in-breds too, going by my knowledge of Europe's Royal families, and Downton Abbey and PG Wodehose ... Drax does have a very 19th century view of what types of humans are superior to whom
