“Deep Blue Sea” reminds me of those late 30’s movies my wife loves to watch on AMC and TCM: It’s slow. It has a small core of key players. It greatly resembles a stage play.

Actually, “Deep Blue Sea” was a stage play! It debuted in London in 1952 and came to Broadway a year later. The movie stars Rachel Weisz as a young woman married to an older man. He is a wealthy London judge. They have a nice life but she wants passion. Her mother-in-law advises her that “restrained enthusiasm” is preferable to passion.

She finds passion with a younger man, a military pilot. She leaves the older guy, moves in with the younger guy, but he (the younger guy) is not quite ready to settle down. He still wants to party in bars, instead of spending all his time with Rachel. This makes her gloomy.

Will she go back to the older guy? Will she follow the younger guy across the ocean? Will she kill herself? No spoilers here!

Director Terrence Davies has turned in a movie that has many stylish shots, including those at the beginning and end of the narrative that frame the film.

Tom Hiddleston plays the younger guy. Simon Russell Beale plays the judge. They’re good, but this is Rachel Weisz’s movie.

If you want an antidote for loud, fast-paced movies with plots that are hard to follow, check out “Deep Blue Sea.” It’s more about the characters and their needs and desires than it is about the plot. And it’s slow. Not that there’s anything wrong with that.

Rated “R” for a nude scene. Opening date for “Deep Blue Sea” has been pushed back to Friday, April 20 at the Plaza Frontenac Theatre.
