Yes Day is a 2021 American family comedy film directed by Miguel Arteta, from a screenplay and screen story by Justin Malen, based upon the children's book of the same name by Amy Krouse Rosenthal and Tom Lichtenheld.

Carlos and Allison present the idea to their family, telling them that if they don't get into trouble, do their chores, and keep their grades up, they can have a yes day as a reward.

The first three are Ellie dressing her parents in crazy outfits and requesting that they don't look at anything with a screen on it all day, ordering a massive $40 sundae that is free if they can eat it all in 30 minutes (they do), going through a car wash with the windows down, and entering a capture-the-flag competition, where each family member leads a group; the goal is for one team to catch the others, throwing balloons filled with Kool-Aid at their opponents.

Carlos, however, is tempted to drop out of Yes Day, but ultimately decides he can't bear to disappoint his family.

In an attempt to win a pink gorilla for Katie as an apology, Allison and Carlos get into a fight with another park-goer and are arrested.

Carlos arrives home and finally manages to be a disciplinarian, forcing the party to stop and the children to help with the cleanup.

They all spend the night playing games as a family in a tent in the backyard, until Nando's foam bomb (having been flushed down the toilet) starts to fill up the house.

In a mid-credits scene, the Torres family and other players pelt Mr. Deacon with Kool-Aid balloons at the Capture the Flag field as revenge for suggesting Yes Day in the first place.

In September 2018, it was announced that Jennifer Garner had joined the cast of the film, with Miguel Arteta directing from a screenplay by Justin Malen, with Netflix distributing.

The website's critics consensus reads, "Yes Day fails to take full advantage of its wish-fulfillment premise, aiming for family fun but settling for harmlessly mediocre.
