According to one source, Karen Allen‘s appearance in "Indiana Jones 4" is pretty much a done deal, although Paramount won’t comment one way or the other.
I don’t know about you, but I’m getting a little tired of all the silly secrecy. Hell, they won’t even give us the title. But CHUD.com seems to be pretty damn sure that "Raiders of the Lost Ark" heroine Karen Allen will be involved in the fourth adventure of Indiana Jones … and she’ll be playing the mommy to Shia LaBeouf‘s character.
"Karen Allen will be reprising the role of Marion Ravenwood in Indiana Jones IV, and she’s going to be Shia LaBeouf’s mom. And you’ll recall that Shia is Indy’s son. You do the math," is what CHUD’s Deven Faraci had to say, and he certainly seems to be a confident source of "Indy" news these days.
