From www.imdb.com: Actress Calista Flockhart is apparently planning to team up with boyfriend Harrison Ford in the next Indiana Jones movie. Filming on Indiana Jones 4 is due to begin in May 2004, with the film looking more adult than its 1980s predecessors. A source says, "Harrison Ford had only one demand when he was approached about doing a fourth Indiana Jones movie - that Calista be written into the new movie. Luckily, Steven Spielberg and George Lucas loved the idea. They think Calista will be a perfect romantic interest for Indiana." And having the ex-Ally McBeal star on board solved one problem for the filmmakers. The source says, "The Indy team had no idea what to do with Indy for the fourth movie. Bringing Calista on board gave them inspiration and they dreamed up the whole story in just a few hours. Getting Calista into the movie was the kick-in-the-pants the guys needed."
