There's really no upcoming movie more worth your anticipation and excitement than the untitled project Paul Thomas Anderson is working on, the story widely believed to be based on Scientology founder L. Ron Hubbard. Aside from simply being the next project from the always fascinating Anderson, the movie had already assembled a killer cast-- Philip Seymour Hoffman in the lead, Jeremy Renner as his sidekick, and who knows what other kind of Anderson regulars to fill in side roles.

So how would Reese Witherspoon being added to the cast change your feelings about it? The Playlist picked up a report in the print edition of Production Weekly that claims Witherspoon has been offered a role in the film, which starts production in June. It's not clear what the role might be, and given that The Playlist has read the script and wasn't able to find too many substantial female roles, it's hard for them to imagine what role Witherspoon might actually play. Then again, scripts change, and we know so little about what Anderson is up to that things could have changed drastically since the draft The Playlist saw.

Witherspoon is currently starring in the film adaptation of Water for Elephants, which just started filming and presumably wouldn't leave her free to play a major role anyway. So maybe she really is popping in for a cameo, maybe because she was such a fan of There Will Be Blood? It seems unlikely, sure, but Witherspoon has proven she has smart instincts in the past-- maybe she really is making a run toward the arthouse.
