Despite reports on the various projects he’s had brewing for some time, Guillermo del Toro remained predictably unpredictable when he recently decided to move forward on a project that no one knew much about. We do know it’s a Cold War romance with a fantasy element, and we know it stars Sally Hawkins and Octavia Spencer — and if this new report is to be believed, then we may also know a few more details, including a new cast member and a title.

In their recent report on Michael Stuhlbarg’s casting, THR described del Toro’s latest as “a mysterious and magical journey set against the backdrop of Cold War-era America circa 1963 with an otherworldly love story at the center of it.” A period drama with dark fantasy elements? Definitely the work of del Toro.

A new report at The Tracking Board claims that the project is titled The Shape of Water, and that Richard Jenkins may be joining the cast. The site also offers some additional plot details, but you should approach all of this with a healthy dose of cautious optimism, as The Tracking Board’s reports can sometimes be a bit off:

… the fairytale, set in 1963, centers around Elisa (Hawkins), a mute janitor working at a lab where an amphibious man is being held captive. When Elisa falls in love with the creature, she devises a plan to help him escape with the assistance of her neighbor (Jenkins). The world outside of the lab, however, may prove to be more dangerous for the amphibious man than Elisa could have anticipated.

If true, would Stuhlbarg be playing the role of the merman? If so, that’s brilliant casting — he’s one of the absolute best character actors, and his ability to bring depth to eccentric roles is somewhat undervalued (as is his handsomeness, in my opinion).

Again, take all of this with a little skepticism, but that’s a fairly plausible plot description. With production set to begin this August, we should know something more substantial pretty soon.
