This is the plot summary:
A young man gets the job of his dreams, only to have his boss move in with him and his roommates after the boss's marriage falls apart. He has so much fun with the younger crowd that he won't leave.
Like The Sitter, this is to be taken with a huge grain of salt, but just doing my job and reporting the possibilities.
The project is set up at Warner Bros. and it has no director attached yet. IMDB lists Matt Nix as the writer and Hollywood.com (which is linked to B/SS) has recently added a second writer to the project, Alan Yang, and his rewrite was confirmed in Variety. Variety also has an article here discussing WB picking up the project.
There is actually another piece of interesting information at Hollywood.com. Apparently Alec Baldwin is also attached to this project. Though it is not specified, it is obviously likely to be the Boss role.
Yet again, wait and see.
