Talk about leaving it to the last minute. With half of the film already shot, and the other half’s production to kick off, supposedly, on March 23rd, Sony has asked David Koepp to polish up the shooting script for the next half of the movie, which sees Will Smith’s Agent J travel back in time to find a young Agent K (Josh Brolin playing a young Tommy Lee Jones) to help save the world.

Now this doesn’t exactly install confidence in the movie, which has already had quite a troubled production, with original screenwriter Etan Cohen (Tropic Thunder) sorting out the concept, Koepp then polished that up and then Catch Me If You Can scribe Jeff Nathanson did work on the second half whilst production was halted. But now Koepp has been brought back to polish that half up as well.

Re-writes are not always a bad thing, some of the best films ever made didn’t have a final shooting script when they went into production (Apocalypse Now for example). And apparently the footage that has already been shot by returning director Barry Sonnenfield, is pretty good with studio execs responding well to it. It may because Koepp did great work on the first half of the movie that the studio want him to do the same for the second half. He just han’t got a lot of time really if they do intend on kick-starting production at the end of the month. But I have to say, the production hardly installs confidence for the upcoming movie, which is still set May 25th 2012.
