In 1996, Kristy Swanson portrayed her in Paramount's big budget film "The Phantom", featuring Billy Zane in the title role. Diana is here sent out by her uncle Dave (in the film, a wealthy newspaper publisher) to Bangalla to help with the search for a fabled weapon of doom, the Skulls of Touganda. When she is trapped by the henchmen of bad guy Xander Drax, she is saved by the Phantom, who unbeknownst to her is really her college boyfriend, Kit Walker. Towards the end of the film (according to the novelisation) she works out the Phantom's true identity based on the fact that he appeared just after Kit disappeared.
