Lee's beauty and talent also caught the eye of international film producer Harry Alan Towers, who gave Lee wider international recognition by casting her in prominent roles in several of his all-star cast productions; starting with the British thriller Circus of Fear (1966), directed by John Llewellyn Moxey. Towers also cast Lee in the spy-comedy Our Man in Marrakesh (1966), directed by Don Sharp; the action film Five Golden Dragons (1967), directed by Jeremy Summers; the thrillers Venus in Furs (1969) and The Bloody Judge (1970), both directed by Jesús Franco; and finally in Dorian Gray (1970), directed by Massimo Dallamano.
