It would be kind of neat if there was a DLC that referenced old time film. I watched metropolis recently and was reminded how great these films are. Perhaps there is a over paranoid inventor who makes an android similar to Metropolis, but this one is meant to fight the communists! There are several directions an idea like this could go. Perhaps a 1920's movie isn't most appropriate for DLC material. But I hope to see references to all the various arts in the 1950's, including film. I know fallout 4 will have some clever quest lines and such.

Not sure if The Day The Earth Stood Still has been referenced before in a Fallout game, but that could be interesting.

We don't even know about 99% of the game, I wouldn't worry about DLC yet.

I noticed that it's over the shoulder ...again. I guess there will be a mod to fix that ...again. Ofcoarse, I expect the customers will have to fix all the bugs and glitches [make it playable] that no doubt, will be found in this game as well. If there will be extentions, please don't dump these quest upon the player as soon as they leave the cave. Let us find them, make a post-it board instead.
