Groups of friends and the crazy games they play seems to be a fun trend at the movies this year. We just had the stellar comedy Game Night starring Jason Bateman. Now, we get Tag, an ensemble that looks as crazy as it's premise. Even weirder, this one's based on a true story. Today, Warner Bros. released the first trailer. And it's bonkers.

One month every year, five highly competitive friends hit the ground running in a no-holds-barred game of Tag they've been playing since the first grade, risking their necks, their jobs and their relationships to take each other down with the battle cry "You're It!" This year, the game coincides with the wedding of their only undefeated player, which should finally make him an easy target. But he knows they're coming...and he's ready.  Based on a true story, Tag shows how far some guys will go to be the last man standing.

Jeff Tomsic directs Tag from a screenplay by Rob McKittrick and Mark Steilen, based on a screen story by Mark Steilen, adapted from the Wall Street Journal article entitled "It Takes Planning, Caution to Avoid Being It" by Russell Adams. The movie has lined up a great ensemble of comedic talent, tagged on the end by the usually much more serious Jeremy Renner in what some are calling the surprise role of the year. And you were worried you weren't going to see enough of him in Avengers: Infinity War.

The cast is led by The Office and Vacation star Ed Helms, who also has a little trilogy under his belt called The Hangover. So he knows his way around this type of comedy minefield. Joining in on the fun are Jake Johnson, Annabelle Wallis, Rashida Jones, Isla Fisher, Leslie Bibb, Hannibal Buress, with Jon Hamm and Jeremy Renner.

The comedy follows what many believe to be the longest running game of tag in history. Though the movie is only loosely based on the exploits of Patrick Schultheis and nine of his childhood friends. The game was thought to be over once these guys and gals all graduated high school. But the whole thing was revived 8 years later at a reunion. Being a first-year lawyer, Schultheis drafted a "Tag Participation Agreement" contract to set some strict ground rules. And the real-life game continues on to this day. Star Ed Helms had this to say to People Magazine about the real-life team of players, along with taking that and turning it into a movie.

"It's just such a sweet premise. It's funny because I feel like it's one of those stories you can only turn into a movie because it's real. If someone came to me with this premise, and was like, 'Yeah, it's a bunch of grownups who play tag,' I would've thought, that's really corny and dumb. But because the guys really do it, suddenly it's really kind of sweet and I don't know, a poignant thing."

Jon Hamm even turns up in the trailer, so there's that! You can check out this riotous game of Tag in the trailer courtesy of Warner Bros. The movie is in theaters later this year.
