Celebrity BACON A GUINEA PIG By People Staff Published on April 6, 1999 12:00 AM Share Tweet Pin Email Kevin Bacon is said to be completing a deal to play the title role in “The Hollow Man,” a drama about an invisible man. Variety says Paul Verhoeven will direct the film, which starts in April. Bacon and Elisabeth Shue will play scientists who were once lovers and who — with another scientist with whom Shue’s character is currently having a romance — discover the secret of invisibility. The guinea pig is Bacon, who begins to use his vanishing act to create havoc. In other casting news, Ben (“There’s Something About Mary”) Stiller will star in Universal’s “Karaoke Knight,” said to be another “Kingpin” — this time set in the world of karaoke. Stiller will play a singer-wannabe whose charisma and stage presence is offset by a terrible voice.
