The career paths of Robert De Niro and Diane Keaton are pretty similar, if you think about it. Both formally starred in some of the greatest movies of all time and collaborated with some of the most talented directors out there only to start taking on bad parts in terrible movies in recent years. The De Niro that made in Taxi Driver under Martin Scorsese is not the same as the De Niro that starred in Little Fockers, and Keaton that made Annie Hall with Woody Allen is not the same Keaton that starred in Because I Said So. That said, the idea of them teaming up for the first time since Marvin's Room might sound good on paper, but I wouldn't get my hopes up.

Variety reports that the pair, as well as Katherine Heigl and Amanda Seyfried, are attached to a new wedding comedy titled Gently Down The Stream. Written and directed by Justin Zackham, the film is about a divorced couple (De Niro and Keaton) who pretend to still be married for the sake of their adopted son on his wedding day. The roles to be played by Heigl and Seyfried are unspecified, though you can probably expect that one of them will play the bride-to-be. Production is scheduled to start in July.

I'm going to close this article out with the following information: before they worked together in Marvin's Room, the last film that featured both Diane Keaton and Robert De Niro was The Godfather Part II. Think about that and then read the plot description for Gently Down The Stream again.
