I have to think it takes a specific sensibility to pull of a Golden Age of cinema parody especially in today’s movie climate. Modern comedies seem content with sticking to tired formulas and they rarely step outside of those boxes. And unfortunately these retreads attract big enough crowds to keep the filmmakers comfortable in the genre’s monotony.

Enter Joel and Ethan Coen, a directing duo who has never played within the conventional or the formulaic. Over the years they have dabbled in a number of genres, never conforming to a popular norm and always putting their own special spin on them. Whether its comedy (“Raising Arizona”), action thrillers (“No Country for Old Men”), westerns (“True Grit”), gangster pictures (“Miller’s Crossing”), or even wild amalgamations of several genres (“Fargo”), the Coen brothers are always approaching things from a unique perspective.

Their latest is “Hail, Caesar!”, a comedy written, produced, edited, and directed by the Coens. The film is set in 1950s Hollywood where big studios still run every facet of moviemaking including their laborers. Josh Brolin plays Eddie Mannix, a real life studio “fixer” represented here with that expected Coen brothers twist. As a fixer Mannix’s job at Capital Pictures is to protect the images of Hollywood stars by hiding their bad and potentially damaging behavior from the public eye.

While the trailer shows off a star-studded cast, this is Brolin’s picture and he does a fine job. The film mainly consists of him managing the studio. The supporting cast is seen through bit parts, some of which are nothing more than glorified cameos. Take Scarlett Johansson, Channing Tatum, Jonah Hill, Tilda Swinton. None have noteworthy screen time and we are only teased with storylines involving each. The best appearances come from Ralph Fiennes and Frances McDormand. They are hilarious but we don’t get enough of them.

The bigger of the supporting roles go to George Clooney and Alden Ehrenreich. Clooney, the Coen’s favorite numbskull, hams it up as Capital Pictures’ biggest star who ends up kidnapped by a mysterious group known only as “The Future”. Ehrenreich plays a singing cowboy (think Gene Autry) who ends up terribly miscast in a stuffy period drama. These story angles, just like the many others, are promising but aren’t given much attention. It all goes back to Mannix and his professional and personal struggles. It is a far cry from the impression left by the trailer.

I don’t mean to sound like “Hail, Caesar!” is a bad movie. It’s not. There are so many winks and tips of the hat to the people and the system that made up Old Hollywood. The film is a veritable collage of homage and parody. Much of it is sure to put smiles on the faces of classic cinema fans. We get a big dance number. We shoot scenes on big studio lots. We see the politics behind making a Ben-Hur-ish prestige film. And of course communism rears its ugly head. All of these things are a lot of fun.

But despite that, there’s something about “Hail, Caesar!” that just doesn’t click. There are so many components to the film that feel underplayed. The Coens have always stuck to their vision, but here their constant wandering from one potential plot point to another gives us several entertaining scenes but not a fully compelling whole. It never can keep a steady momentum and the humor seems to come in a few scattered bursts.

It’s hard to put into words what made the film hard for me to fully embrace. As I said, there are many really good scenes and several specific fun moments that stood out to me. Most feature that signature quirky Coen brothers dialogue that I love. But its hard to find a satisfying narrative thread that brings them together. I can’t help but think that a little less of these out-of-the-blue indulgences and slightly more focus on a central story thread would have helped the film immensely.

Still, a disappointing Coen brothers movie is better than most other comedies of today. That’s one way of looking at it. But that doesn’t cover the one unfortunate fact – “Hail, Caesar!” is still a disappointment. It has its moments (some of them are really great), but its flippant approach to some of the storylines it injects left me feeling a bit slighted.
