An open-relationship comedy with big laughs and a lot of spouses.

If you recall “The Climb,” Michael Angelo Covino told Kyle Marvin that he slept with his fiancée during their bike ride. If you see “Splitsville,” Marvin find out about another tragedy that en route. Boy, this actor sure enjoys playing characters who deal with some unfaithful characters.

The tragedy in “Splitsville” regards Carey (Marvin) being told by his life coach wife Ashley (Adrina Arjona) that she is unfaithful and wants a divorce from him. He runs away and reunites with his married friends-Paul (Covino) and Julie (Dakota Johnson) in their Long Island home. Unlike him, they’re in an opened-relationship, which we all know means they can be together while sleeping with other people.

So that’s the concept of Covino and Marvin’s latest collaboration (the former is the director, and while the latter is the co-writer). And in the independent circuit (“Splitsville” is released by NEON), they have voices in the comedy genre, and they don’t take the easy way out.

It becomes complicated, as Carey sleeps with Julie, while her husband is on business either to score a deal or score with a woman. And when Carey comes home to Ashley, she already has enough ex-lovers staying over. Let’s face it. Carey and Paul have marital problems here. But do we really need to the get the divorce lawyers involved? Not through our perspective, we don’t.

It basically becomes a role reversal for Covino and Marvin, when the former attacks the other for sleeping with his wife. If you did see “The Climb,” and I recommend you do, you would know exactly what I’m talking about. But in “Splitsville,” Covino’s character makes some bad choices that affects his own marriage and his son Russ (Simon Webster). Or the kid could be developing some bad ideas like stealing jet skies and having the owner argue with the adults.

We have the new version of “The War of the Roses” in theaters now called “The Roses.” It was funny, but it wasn’t that original, and it felt desperate towards the end. I’m still adjusting to the ideas in “Splitsville,” but I still think it’s a funny and interesting movie that continues to broaden Covino and Marvin as filmmakers and actors. Some of us know that Marvin has also directed “80 for Brady,” while Covino’s other acting credits include “News of the World” and “Riff Raff.” But seeing their collaborations through their own choices of comedy pathos, they both prove to be capable of anything.

There’s a scene that had me laughing so hard, I’m surprised no one in the audience shushed me. It involves some fish and a fair, but I can’t say what the joke is. You’ll have to see for yourselves. And I did remind me of how Roger Ebert was laughing so hard at the parakeet scene in “Dumb and Dumber.”

I remember “The Climb” having the late George Wendt as the only well known actor in the cast. “Splitsville” has Johnson, Arjonia, and Nicholas Braun as a new lover in the cast. Johnson started the summer successfully with “Materialists,” which had her trying to find perfect romantic spouses. Her new movie struggles to find her a perfect spouse, which is interesting. After all, do open relationships really work? I’ve never met anyone in one of those, but you tell me if they really work. Either way, I think she’s had a good summer with these kinds of movies.

“Splitsville” might detract your attention with the complications and other spouses along the way, but it will keep you involved with the main characters and how their relationships aren’t as romantic as they would have hoped. And I’m still laughing about the fish.
