Karina Longworth

Billionaire filmmaker Howard Hughes has long been regarded as one of Hollywood's most eccentric and prolific playboys. A few years back, writer and film critic Karina Longworth stumbled onto an online message board, listing women Hughes had had sexual relationships with — just a list of names, no other information.

"In each of these names there's a whole life and a whole story," says Longworth, who hosts the film podcast You Must Remember This.
