James Cameron’s “Titanic” was officially sold at the Treasures From Planet Hollywood auction last week for a whopping $718,750. According to Heritage Auctions, the prop was the most bid-upon item despite being surrounded by other iconic pieces of Hollywood’s legacy. In the film, the door is used when Rose (Kate Winslet) and Jack Dawson (Leonardo DiCaprio) attempt to lie on the piece of wood while awaiting rescue shortly after the RMS Titanic sinks.
